    RIPPLE, Circuit Judge. On July 3, 2003, the Highway J
    Citizens Group (“Citizens”) filed this action pursuant to the

    42 U.S.C. § 4321
     et seq.; regulations implementing NEPA; and the
    Wisconsin Environmental Policy Act (“WEPA”), 
    Wis. Stat. § 1.11
     & Wis. Adm. Code ch. TRANS § 400 et seq. The
    named defendants were Norman Mineta, in his official
    capacity as Secretary of the United States Department of
    Transportation (“U.S. DOT”); Frederick Wright, in his of-
    ficial capacity as Executive Director of the Federal Highway
    Administration (“FHWA”); and Thomas E. Carlsen, in his
    official capacity as Acting Secretary of the Wisconsin
    Department of Transportation (“WDOT”) (collectively “de-
    fendants”).1
    Citizens challenged the Ackerville Bridge/Lovers Lane
    Project, Project #2748-01-00 (“Ackerville Bridge Project”)
    and the County J/Highway 164 Project, Project #2748- 01-01
    (“County J/Highway 164 Project”). According to the
    complaint, a “contamination plume” containing arsenic and
    trichlorethylene (“TCE”) is migrating toward the site of the
    Ackerville Bridge. Among other things, Citizens asked the
    district court (1) to enjoin the FHWA and WDOT from
    proceeding with the Ackerville Bridge Project until the
    location and extent of the contamination plume was deter-
    mined, (2) to order the FHWA and WDOT to pump grout
    around the perimeter of pilings that have been driven into
    the ground to support the Ackerville Bridge, and (3) to
    require the FHWA to prepare an Environmental Impact
    Statement (“EIS”) for the Ackerville Bridge Project. On June
    12, 2003, the United States District Court for the Eastern
    District of Wisconsin denied Citizens’ motion for a prelimi-
    1
    The FHWA, the federal agency in this case, worked in con-
    sultation with WDOT, the funding applicant, in performing the
    tasks required by NEPA. See 
    23 C.F.R. § 771.119
    .

    nary injunction and then ruled against Citizens on the
    merits. On June 13, 2003, the district court denied Citizens’
    expedited motion for stay pending appeal.
    Citizens filed its notice of appeal on June 17, 2003. It then
    asked this court for an emergency injunction to prevent the
    opening of the Bridge. This court denied the requested
    relief, but granted Citizens’ motion for an expedited appeal.
    In this appeal, Citizens seeks (1) a permanent injunction
    requiring closure of the Ackerville Bridge until grout is
    pumped around the pilings, (2) an EIS of the Ackerville
    Bridge Project, and (3) a revised EIS of the County
    J/Highway 164 Project that encompasses the area of the
    Ackerville Bridge Project and a permanent injunction
    prohibiting the County J/Highway 164 Project from pro-
    ceeding until the revised EIS is completed. For the reasons
    set forth in this opinion, we must deny Citizens the re-
    quested relief and affirm the judgment of the district court.

    BACKGROUND
    A. Facts
    There are two projects at issue in this case; both are
    “major federal action[s]” as defined in 
    40 C.F.R. § 1508.18
    .
    Highway J Citizens Group is an unincorporated association
    of residents of Waukesha and Washington Counties in
    Wisconsin who are “committed to preserving the beauty,
    tranquility, and environment of the area.” R.1 at ¶ 1.
    Specific to this litigation, Citizens also includes persons
    “who live in the area of the proposed Ackerville bridge and
    whose water supply is threatened with contamination from
    arsenic and TCE as a result of the proposed Ackerville
    bridge project.” R.1 at ¶ 1. Thus, Citizens’ focus in this case
    4                                                   No. 03-2644
    is Project #2748-01-00, the Ackerville Bridge Project. Project
    #2748-01-01, the County J/Highway 164 Project, is relevant
    to this litigation only because Citizens believes that it was
    improperly segmented from the Ackerville Bridge Project.
    1.     The Ackerville Bridge Project (Project
    # 2748-01-00)
    There are three purposes for the Ackerville Bridge Project.
    The “primary purpose” is to address safety considerations
    flowing from the layout of the roads and the close proximity
    of the railroads. R.38, Ex.1003, A.R. at 00004. Another
    purpose is to bring the existing facility into compliance with
    State Trunk Highway standards, which govern the neces-
    sary requirements for a road to support truck traffic. 
    Id. at 00013
    . A “secondary purpose” is to provide for future
    expansion of the roadways due to increasing traffic in the
    region. 
    Id. at 00004
    . To affect these purposes, the plan
    provides
    an overpass structure . . . to be built at the Wisconsin
    Central Limited and the Wisconsin Southern Railroads
    in order to remove the existing at-grade crossings. The
    Sherman Road/Fond du Lac Drive connection would
    also be located under this structure. An additional
    overpass would be provided at State Highway 175.
    
    Id. at 00012

    The environmental assessment (“EA”) for this Project was
    signed by various state and federal officials between
    October 29, 1999, and December 12, 1999, and was open for
    public comment from February 22, 2000, to April 7, 2000. 
    Id. at 00004

    discussion of the former waste disposal facility (“landfill”)
    near the Project that was owned by Waste Management
    Company of Wisconsin, Inc. This landfill is located about
    2,000 feet northwest of Ackerville and is leaking “landfill
    leachate” which has contaminated the underlying ground-
    water that flows from the landfill. As the contaminated
    groundwater flows, the contamination can spread or
    disperse, and this dispersed contamination is known as
    “contamination plume.”
    The effect of this contamination plume on the Ackerville
    Bridge Project was brought to the attention of the defen-
    dants by Jeffrey Gonyo, a member of Citizens, sometime
    during, and possibly before, February of 2000. R.38, Ex.1013,
    A.R. at 00838 (Wade e-mail); R.38, Ex.1005, A.R. at 00146-
    00147 (draft “Fact Sheet/Topics of Interest”). Defendants’
    initial conclusion was that the contamination plume did not
    raise significant concerns in relationship to the Ackerville
    Bridge Project. For example, in a February 21, 2000 docu-
    ment entitled “Fact Sheet/Topics of Interest,” defendants
    stated:
    • The Waste Management Landfill-Hazardous Materials.
    If there is contamination in the shallow groundwater,
    couldn’t the structure pilings create a “channel” to
    contaminate [sic] the deep groundwater where our
    drinking water comes from?:
    • Acknowledge that both Wisconsin Department of Natural
    Resources and WDOT are aware of the concerns relating to
    the Polk Landfill. You can thank Mr. Gonyo for helping to
    bring the issue to the forefront.
    • WDOT will be addressing the contaminant concerns relating
    to the STH 164 project as part of the Phase 1 hazardous
    materials assessment. The assessment will evaluate [W]DNR
    documents about the landfill and assess what impact may be
    associated with the highway project activities. The WDOT
    6                                                      No. 03-2644
    will coordinate with the WDNR as needed. The report will
    include any recommendations that may be needed to address
    [hazardous materials] concerns.
    • The Phase 1 Assessment Report will become a public doc-
    ument available for review.
    • Though preliminary assessment of available information has
    led [sic] both [W]DNR and WDOT to think there are not
    likely to be significant project hazmat concerns related to the
    Polk Landfill, it would be premature to make definitive
    statements until the Phase 1 report is completed.
    R.38, Ex.1005, A.R. at 00143-00144 (italics in original). A
    previous, draft version of that document, dated February 15,
    2000, addressed the environmental question posed as
    follows:
    • This landfill was closed in the 1980’s. Since that time,
    extensive monitoring and remediation has taken place. There
    has been some concern regarding the ground water contami-
    nation spreading in the direction of Lovers Lane Road.
    However, the project requires limited excavation in the area
    (footing for substructure units of the bridge) and encounters
    with ground water is unlikely.
    R.38, Ex.1008, A.R. at 00146. In a March 14, 2000 letter from
    Ken Wade, Hazardous Materials Engineer for the Environ-
    mental Team, Transportation District 2 of WDOT, to EMCS
    Design Group, Mr. Wade noted:
    I’ve attached copies of the latest landfill data collected
    by Waste Management. It clearly confirms that the
    concentration of [TCE] nearest the project area is
    decreasing and stable. The groundwater monitoring
    well nearest the project corridor is TW23R, located
    approximately 400 feet west of CTH J. TCE concentra-
    tions in well TW23R have dropped from 3 to 2.2 ug/l,
    No. 03-2644                                                  7
    well below the WDNR groundwater enforcement
    standard of 5 ug/l.
    The water table for this region is approximately 30 feet
    below the ground surface. If construction plans for the
    footings require only 4 to 5 feet of excavation, it is very
    unlikely that contaminated groundwater will impact the
    project.
    It is also unlikely that project pilings or water deten-
    tion/infiltration basins will cause an impact on plume
    movement or concentrations.
    R.38, Ex.1009, A.R. at 00728.
    At the March 23, 2000 public hearing on the Ackerville
    Bridge Project, Mr. Gonyo testified in opposition to the
    Project. Among other things, he identified the landfill as a
    source of contamination that the Project threatened to
    aggravate. With the aid of numerous exhibits, he testified
    that: (1) the Project goals could be accomplished by simpler
    and less costly means, (2) the Ackerville Bridge Project
    should not be segmented from the County J/Highway 164
    Project, and (3) the landfill contaminants pose great risks in
    conjunction with the Project.
    On April 7, 2000, the “Hazardous Materials Site Inves-
    tigation Report Phase I Addendum” (“Addendum”) was
    released. R.38, Ex.1015, A.R. at 00709-00714. This Adden-
    dum was prepared by the EMCS Design Group, which
    worked in connection with the WDNR in developing the
    report. The Addendum is based on a review of the March
    30, 1990 report entitled “Two-Year Ground Water Monitor-
    ing Report Polk Sanitary Landfill Washington County,
    Wisconsin.” This report discusses the groundwater around
    the landfill, including its flow, contains maps and discus-
    sions of arsenic and TCE, and concludes that the landfill
    was not the source of downgradient TCE detections or
    8                                               No. 03-2644
    elevated arsenic levels. R.38, Ex.1000, A.R. at 02774-02814.
    The 2000 Addendum is also based on a review of the “Phase
    I and Phase II Hazardous Material reports,” R.38, Ex.1014,
    A.R. at 00873-00908, which “were completed in 1994 for this
    project based on” the originally conceived limited scope of
    the Project, which did not include a bridge. R.38, Ex.1015,
    A.R. at 00710. The “February 23, 1994 Phase I Report”
    identified groundwater in the area as potentially contami-
    nated and noted that WDNR was continuing to monitor it.
    It added, “The groundwater depth should be determined
    within the project limits so that excavation to the groundwa-
    ter depth during construction can be avoided.” R.38,
    Ex.1014, A.R. at 00876. In the Addendum, the landfill is
    addressed as follows:
    Site 7 (previous): Town of Polk/Waste Management
    (WDNR FID # 267062400) was identified in the original
    phase I report as an inactive waste disposal site. There
    is groundwater contamination in this area with [TCE]
    being one of the contaminants. The closest monitoring
    well is located approximately 400 feet west of STH 164.
    TCE concentrations in this well have dropped from 3 to
    2.2 ug/l, well below the WDNR groundwater enforce-
    ment standard of 5 ug/l. This site is 700 feet west of
    where the proposed Foxboro extension connects to STH
    175 and indicated groundwater depths of 30 feet are
    well below the excavation limits of the roadway.
    Therefore, it is very unlikely that the contaminated
    groundwater will impact this project. It is also unlikely
    that the pilings for the structure supports or retention
    basins will cause an impact on plume movements or
    concentrations.
    R.38, Ex.1015, A.R. at 00714.
    On April 25, 2000, the last signature was placed on the
    “Finding of No Significant Impact” (“FONSI”) for the Proj-
    ect. The FONSI was premised on the EA for the Project,
    No. 03-2644                                                   9
    which was attached to the FONSI. The final EA/FONSI
    contains a “Basic Sheet A” which includes the comments
    from the public on the Project and defendants’ responses to
    the comments. Specifically, Basic Sheet A considers whether
    the landfill “is a significant impact and therefore warrants
    preparation of an EIS,” but concludes the landfill “will not
    affect the Department’s proposed project.” R.38, Ex.1003,
    A.R. at 00005. It explained:
    There is ground water contamination in the area sur-
    rounding the landfill with [TCE] being one of the
    contaminants. This site has been under remediation for
    several years. The closest monitoring well is located
    approximately 122 m (400 ft) west of STH 164. TCE
    concentrations in this well have dropped from 3 to 2.2
    ug/l, well below the WDNR groundwater enforcement
    standard of 6 ug/l. Indicated ground water depths of
    9m (30 ft) are well below the excavation limits of the
    roadway or bridge construction.
    The Department has determined that the potential for
    encountering and impacting hazardous materials dur-
    ing construction of this project does not exist. Therefore,
    there is no purpose or need for preparation of an EIS.
    
    Id.
     The EA/FONSI also responded to Citizens’ suggestion
    that the Ackerville Bridge Project and the County
    J/Highway 164 Project be joined together as one EIS. After
    considering the three criteria for segmentation set out in
    FHWA regulations, see 
    23 C.F.R. § 771.111
    (f)(1)-(3), it
    concluded that “the selected alternative has logical termini,
    independent utility, and does not preclude or exclude future
    alternatives for other projects. It is therefore appropriate
    that [the Ackerville Bridge Project] be allowed to stand on
    its own merit.” 
    Id. at 00004
    . The EA/FONSI also considered
    alternatives, including the alternative proposed by Citizens,
    but concluded that the best alternative to effectuate all of the
    10                                               No. 03-2644
    purposes of the Project includes the Ackerville Bridge. 
    Id. at 00006, 00013
    .
    On July 7, 2000, Mr. Gonyo sent a letter to Paul Tufts, an
    environmental specialist at the FHWA, requesting that the
    defendants reconsider the FONSI and that an EIS be pre-
    pared before any construction on the Project. This letter
    specifically notes as a concern that “the pilings will have to
    be driven into and below the contaminated groundwater
    table.” R.38, Ex.1017 at 2. According to the defendants,
    Richard Madrzak of the FHWA requested information from
    Jay Waldschmidt of the WDOT, Bureau of Environment, to
    respond to Mr. Gonyo. R.29 at 10. During their oral conver-
    sation, Mr. Waldschmidt discussed previous conversations
    with Chad Czarkowsi and Phil Fauble of WDNR, and then
    Mr. Madrzak asked to have something in writing. 
    Id.
    On August 22, 2000, the WDNR provided the WDOT a
    memorandum, per the request of Mr. Waldschmidt, in re-
    sponse to the groundwater concerns. R.38, Ex.1020, A.R. at
    12294. The authors of the memo are Chad Czarkowski and
    Phil Fauble, both of whom have extensive experience with
    groundwater issues with WDNR. This 2 ½ page, single-
    spaced memo has as its main conclusion that “the road
    project will not have any substantial effect [sic] on the
    existing pattern of groundwater flow, concentration of
    contaminants, nor cause any increase in health risks due to
    ground water contamination in the vicinity.” 
    Id. at 12295
    . In
    support of that conclusion, the memo noted that
    [t]he TCE seems to originate from a point approxi-
    mately 1500 feet west / northwest of Hwy 164 and
    Sherman Road. Groundwater flow has been determined
    to be southeasterly from the apparent source, towards
    the proposed road project. The top of the water table in
    the gravel aquifer below the road project area is approx-
    imately 30 feet below the land surface.
    No. 03-2644                                                 11
    
    Id.
     As to the concentrations of TCE, the memo stated that in
    the mid-1980s, area wells had been tested for TCE, and
    levels exceeded Wisconsin’s enforcement standard of 5
    ug/l. 
    Id.
     However, the landfill “is not considered a likely
    source of the TCE plume because TCE has not been detected
    in either the landfill leachate or consistently in monitoring
    wells directly adjacent to the landfill.” 
    Id.
     The memo further
    noted that the private wells determined to be at risk from
    the waste disposal sites were sampled in the 1980s, and they
    were subsequently either abandoned altogether, abandoned
    and replaced with “deeper dolmite aquifer wells cased to
    the top of the first bedrock at 220 feet,” or sampled and
    found clean. 
    Id.
    Finally, the memo considered three mechanisms by which
    the project could conceivably affect groundwater in the
    vicinity. The one relevant to this appeal is: “Driving pilings
    to depths greater than 30 feet could potentially encounter
    contaminated groundwater.” 
    Id. at 12296
    . On this issue, the
    memo concluded that
    such vertical steel pilings would not, in themselves,
    contribute any additional contaminants to the ground-
    water, nor significantly alter flow along any horizontal
    plane. Theoretically, the flow of groundwater could be
    altered along vertical lines due to penetration of a piling
    thru lenses or layers of dense, clay-rich soil known as
    “confining layers” or aquatards. Such layers, if present,
    normally act to prevent downward or upward move-
    ment of groundwater. A piling might compromise a
    confining layer by creating a narrow (0.5”-3” maximum)
    concentric space along the outside shaft of a piling or
    casing.
    However, we believe the placement of pilings will not
    significantly affect ground water conditions on this
    project. As documented by well logs and soil borings,
    12                                                 No. 03-2644
    there is no effective, continuous confining layer in the
    project area. Without any effective separation of the
    shallow sand and gravel aquifer from the deeper
    dolomite aquifer, ground water already moves freely
    along vertical planes. In fact, several well nests near the
    proposed project record consistent upward gradients,
    an indication that deeper aquifer water is discharging
    into the shallower system. The relatively small increase
    in vertical groundwater movement which might be
    expected along open spaces surrounding even several
    dozen pilings is insignificant compared to the quantity
    of natural vertical movement.
    In conclusion, there does not appear to be any mech-
    anism by which the existing groundwater conditions
    will be significantly altered by the road project.
    
    Id. at 12296-12297
    . On August 23, 2000, Mr. Madrzak sent an
    e-mail to Paul Tufts, the addressee on Mr. Gonyo’s letter
    requesting reconsideration of the FONSI, discussing the
    August 22, 2000 memo:
    Attached for your information is a copy of DNR’s
    response to my request through Jay Waldschmidt for
    information regarding Mr. Gonyo’s allegation that the
    project will have a significant effect on the environment
    with regard to hazardous materials.
    The DNR note confirms the information contained
    in the revisions to the Environmental Assessment. The
    FONSI remains valid despite Mr. Gonyo’s objections.
    We will respond accordingly to his request for FHWA
    to withdraw approval of the FONSI.
    His other concerns regarding segmentation are ade-
    quately discussed in the revisions to the EA.
    R.11, Ex.5 (attached e-mail). On August 24, 2000, the FHWA
    sent a letter to Mr. Gonyo responding to his July 7, 2000
    No. 03-2644                                                13
    letter. In accord with Mr. Madrzak’s e-mail, this letter
    concludes that the April 2000 FONSI/EA remains valid and
    meets the intent and requirements of NEPA.
    Citizens expressed its concerns to the United States
    Environmental Protection Agency (“U.S. EPA”) in various
    petitions in the first five months of 2000, and on August 28,
    2000, the WDNR sent a letter to Jan Pels of the U.S. EPA
    explaining its conclusions regarding the extent of the
    contamination plume and the Project’s effect on the plume.
    R.38, Ex.1023, A.R. at 10166-10171. The letter concluded that
    “[t]here is no evidence that existing private water supply
    wells are being impacted by groundwater.” R.38, Ex.1023,
    A.R. at 10171. As to the Project, it stated in full: “The WDNR
    has also determined that the proposed WDOT road expan-
    sion and bridge project on STH 164 will not have an adverse
    impact on the ground water in the Ackerville area. The
    rationale for this determination is detailed in the attached
    memo from WDNR to WDOT.”

     On January 12, 2001, the
    U.S. EPA sent Mr. Gonyo a letter regarding his request for
    an investigation of the Waste Management landfill. The
    letter stated that the WDNR is in the process of “preparing
    a Sampling and Analysis Plan for a [Site Inspection] of the
    Old Town Dump site.” R.38, Ex.1024, A.R. at 10164-10165.
    This “Old Town Dump site” is a landfill just south and
    across the tracks from the Waste Management landfill, and
    the WDNR and U.S. EPA believed this landfill may be the
    actual source of the contamination. 
    Id. at 10164
    .
    On January 22, 2001, John E. Thresher, Jr., Citizens’
    groundwater expert, provided Fauble with criticisms of
    WDNR’s groundwater analysis at the Waste Management
    landfill. This report discussed the extent and source of the
    TCE, concluding a “reasonable case can be made” the Waste
    Management landfill is the source. R.39, Ex.1025, A.R. at
    12301-12304, 12307-12308. It also discussed arsenic, which
    14                                              No. 03-2644
    the report explained was in the vicinity of the landfill and
    migrating toward Ackerville, and explained that the degree
    and extent of arsenic is not known due to various factors.
    The letter concluded with a strong request that an EA be
    performed to address these concerns. The letter did not
    discuss the Ackerville Bridge Project.
    On February 26, 2001, EMCS Design Group issued a
    report officially acknowledging the pilings for the Project
    would extend below groundwater level. On July 10, 2001, a
    public hearing was held regarding WDOT’s petition to the
    Office of the Commissioner of Railroads of the State of
    Wisconsin (“OCR”) for alteration and closure of crossings
    for purposes of the Ackerville Bridge Project. At this
    hearing, Mr. Gonyo and other citizens testified about their
    concerns regarding the environmental impacts of the Proj-
    ect, and Mr. Thresher, Citizens’ expert, testified as to his
    conclusions. Mr. Bauman of WDOT also testified. On July
    11, 2001, Mr. Thresher sent a follow-up letter to the hearing
    examiner at the OCR hearing. In that letter, he restated his
    position that contaminated water is moving towards
    Ackerville and that “[d]riving pilings through such sedi-
    ments may disrupt the contaminant distribution thereby
    potentially contaminating additional private wells within
    Ackerville.” R.39, Ex.1028, A.R. at 14559-14560.
    In an e-mail dated July 26, 2001, Mr. Bauman of WDOT
    referenced a June 2001 article in Civil Engineering analyzing
    the environmental impact of pilings placed into contami-
    nated soil entitled “Deep Foundations on Brownfield Sites.”
    This article concluded, among other things, that “driven
    piles can be used on even ‘brownfields’ sites without
    causing adverse environmental effects. However, the proper
    type(s) of piles must be selected to avoid such effects . . .
    such as steel and possibly concrete to avoid internal flow.”
    R.39, Ex.1030, A.R. at 13833.
    No. 03-2644                                               15
    Mr. Czarkowski of the WDNR, one of the authors of
    the August 22, 2000 memo that found the pilings would
    have only an insignificant effect on the groundwater, re-
    sponded to Mr. Bauman by e-mail: “When I first reviewed
    the environmental concerns regarding this project as part of
    the team here at DNR, I was aware that pilings would be
    driven below depths of 30 feet, which is where the ground-
    water occurs. We do not dispute that a very low level of
    [TCE] may exist in the groundwater.” R.39, Ex.1031, A.R. at
    13827. Mr. Czarkowski went on to state that his opinion that
    the pilings would not in any way affect groundwater flow
    was based on the assumption the pilings would be filled
    with solid material. He wanted to ensure that such was the
    case so he could maintain his opinion, memorialized in the
    August 22, 2000 memo, that the pilings “should not provide
    a significant pathway for migration of groundwater.” 
    Id.
    Mr. Bauman responded to Mr. Czarkowski on August 27,
    2001, and confirmed that the pilings would be filled with
    concrete. 
    Id.
    On September 20, 2001, the WDOT attended a meeting
    called by Wisconsin State Representative Suzanne Jeskewitz
    to discuss Mr. Gonyo’s testimony at the OCR hearing.
    WDOT’s “Public Communication Record” described the
    meeting in its “Discussion Summary”:
    Began to discuss parts of Mr. Gonyo’s testimony (13
    points), but only completed first one on project cost and
    bridge size. Discussion then went to John Thresher’s
    statements on potential impact of bridge piling on local
    groundwater contamination. Mr. Thresher states that in
    his opinion the WisDNR did not do a sufficient amount
    of study to determine the location of the contaminants
    and that the bridge piling could transfer the contamina-
    tion to area wells.
    A.R. at 10453. In the “Point Made” section of the Record, it
    16                                             No. 03-2644
    stated in relevant part: “WisDOT did not agree with Mr.
    Thresher’s assertion that contaminated groundwater in the
    area could be impacted by our project. WisDNR has told
    WisDOT that pilings from the proposed structure will not
    cause contamination to spread to neighboring wells.” 
    Id.
    On October 19, 2001, the OCR issued a final decision
    granting the petition of the WDOT to alter and close the
    railroad tracks in the vicinity of the project. In its final
    report, the OCR laid out the pilings issue and WDOT’s
    analysis of the issue, as supported by WDNR. It concluded:
    “The environmental issues raised by the opponents have
    already been adequately addressed by the environmental
    assessment done by DOT. Requiring another EA or a full
    EIS would only serve to delay an important safety project
    without any likely environmental benefit.” R.39, Ex.1027,
    A.R. at 14112.
    On October 24, 2001, WDOT and WDNR representatives
    attended the follow-up meeting to the September 20, 2001
    meeting held by Rep. Jeskewitz regarding the contamination
    and environmental effects of the project. One of the Public
    Communication Records in the record includes a “Discus-
    sion Summary” which described the substance of the
    meeting:
    SURE expert John Thresher’s position:
    • Alleges that groundwater contamination plumes (TCE
    and Arsenic) are approaching STH 164.
    • Contends that pilings from new bridges would be a
    mechanism for contaminated groundwater to enter
    area wells (offered no proof).
    • Believes that Waste Management Landfill is source of
    contamination.
    • Wants groundwater monitoring wells installed in STH
    No. 03-2644                                              17
    164 right-of-way to determine if contamination is
    present.
    • If contamination is not within right-of-way, pilings
    will not cause contamination to enter area wells.
    WisDNR’s position:
    • Site has been monitored since about 1980. Contamina-
    tion is present in shallow groundwater.
    • Mr. Thresher’s information is based on 1986 data,
    which is considered suspect.
    • Based on existing site conditions, pilings could not be
    a mechanism for the contaminated groundwater to
    enter area drinking wells.
    • There is no proof that contamination is migrating to-
    wards STH 164. Appears that concentration of con-
    tamination is reducing as expected.
    • There is no definitive evidence that Waste Manage-
    ment Landfill is source of contamination.
    • Don’t believe monitoring wells are needed and can’t
    legally make Waste Management install them.
    • Recommend continued testing of private drinking
    water wells and replacement if problem occurs.
    WisDOT’s position:
    • Have support from all the required agencies and have
    followed all environmental requirements.
    • Concur with WisDNR’s position on pilings.
    • Cited article in ENR Magazine of study done by
    University of New Orleans that displacement piles
    would not likely form conduits for contamination
    transfer (we are using cast-in-place concrete piling—
    18                                              No. 03-2644
    a displacement pile).
    Rep. Jeskewitz and Sen. Darling will send letter to
    WisDOT requesting installation of monitoring wells in
    STH 164 right-of-way.
    A.R. at 10440. In the next “Point Made” section of the
    Record, it stated: “WisDNR and WisDOT believe there is
    adequate proof to indicate that contamination has not
    migrated to the STH 164 right-of-way nor will contamina-
    tion in excess of Health Advisory Limits ever migrate to the
    right-of-way. Further, pile driving will not cause migration
    even if contaminants are present.” 
    Id.
    On November 16, 2001, Mr. Gonyo sent a letter to
    Terrence Mulcahy, then-Secretary of the WDOT. 
    Id. at 10586
    .
    This letter discussed a Town of Polk resolution opposing the
    Ackerville Bridge Project and requested that the Project be
    immediately ended. 
    Id.
     A December 3, 2001 letter from
    Secretary Mulcahy responded by acknowledging the
    opposition but noting that safety is the primary goal of
    WDOT and the bridge option provides for the best effectua-
    tion of safety and other goals for the Project. 
    Id.
     at 10587-
    10588.
    On December 11, 2001, the WDOT received another
    inquiry from Wisconsin State Representative Michael
    (Mickey) Lehman asking whether there was any plan to
    clear up the contamination plume and whether additional
    testing was possible. The WDOT responded on December
    21, 2001, recognizing the concern but concluding:
    The DNR has stated that the driving of piling into the
    groundwater will not cause contamination to migrate
    into area wells. Based on these statements from the
    DNR, our position is that if drinking water well contam-
    ination occurs, it will not have been caused by our
    project and would fall under the jurisdiction of the
    No. 03-2644                                              19
    DNR. Therefore, I am forwarding your letter to Charles
    Krohn, Southeast Region Water Leader, DNR, and
    asking that they respond to your questions, since they
    are experts on handling groundwater contamination.
    
    Id. at 10575
    .
    On December 13, 2001, the U.S. EPA sent a letter to Mr.
    Gonyo responding to his letter explaining the “Resolution
    of the Town of Polk Electors Opposing the Ackerville
    Bridge” Project and the County J Project. This letter stated
    that based on the information it had received from WDNR,
    WDOT and FHWA, U.S. EPA believed the potential con-
    tamination issues had been addressed adequately in the
    respective EA and EIS for these projects. 
    Id. at 10477
    . The
    letter also responded to Mr. Gonyo’s request for a Federal
    Superfund cleanup of the entire landfill area west of
    Ackerville, Wisconsin. In that regard, the letter noted that
    the environmental investigation report that U.S. EPA con-
    ducted on the site revealed no direct contact threats to the
    soil at the site and that there is no observed release of
    groundwater that can be attributed directly to the site. 
    Id.
    “Therefore, the U.S. EPA did not recommend further
    investigation of the subject landfill.” 
    Id.
    Another public meeting on the contamination plume was
    held on January 30, 2002, at which State Representatives and
    Senators requested installation of monitoring wells in
    Ackerville. In a February 4, 2002 document entitled “Sum-
    mary of the Groundwater Contamination in the Ackerville
    Area Washington County, Wisconsin,” Mr. Thresher again
    concluded that the contamination threatened Ackerville
    residents and discussed the pilings. On February 26, 2002,
    a document entitled “Public Health Assessment for
    Ackerville Area Groundwater” was released by the Wiscon-
    sin Department of Health and Family Services, Division of
    Public Health, on behalf of WDNR, the Washington County
    20                                               No. 03-2644
    Health Department, and the Agency for Toxic Substances
    and Disease Registery. The Assessment concluded: “There
    is no relationship between the proposed bridge construction
    project and area groundwater quality. The groundwater is
    30 feet below the ground surface and will not be affected by
    the bridge or road construction.” R.38, Ex.1039, A.R. at
    10154.
    On February 27, 2002, then-WDOT Secretary Gene E.
    Kussart sent letters to the various state Representatives and
    Senators who had requested testing at the January 30, 2002
    meeting, stating: “Although the [WDOT] has conformed to
    all environmental requirements for this project and [WDNR]
    and [FHWA] have indicated that our improvement project
    will not impact the groundwater, I have decided to accom-
    modate your request.” R.39, Ex.1036, A.R. at 10545-10548.
    These wells were installed by STS Consultants in the
    vicinity of the Project for the purpose of “determin[ing]
    potential impacts of upgradient groundwater contaminant
    sources on areas of bridge pile support installation.” R.39,
    Ex.1038, A.R. at 10086. In an April 8, 2002 memorandum to
    “Files,” Mr. Bauman of WDOT noted the wells should be
    installed before construction and tested within a week of
    installation and quarterly for two years thereafter. The
    memo also noted:
    WisDOT intends to turn over the results of all tests to
    the WisDNR for their use. It is our opinion that the
    WisDNR will be responsible to pursue and oversee any
    actions needed in response to the test results. The
    WisDOT, Dept. of Health and Family Services and the
    WisDNR all believe this project will not impact the
    groundwater in the project area whether contamination
    is present in the right-of-way or not. Therefore, we ex-
    pect that regardless of what is found in the tested wells
    the project will not be delayed or changed in any way.
    No. 03-2644                                                 21
    R.39, Ex.1039A, A.R. at 10119. In an e-mail dated April 24,
    2002, Mr. Wade of WDOT reached the following conclusion
    based on the initial sampling results from the new monitor-
    ing wells:
    The confirmation of permeable aquifer materials,
    upward hydraulic gradients, low contaminant con-
    centrations, and lack of any apparent contaminant
    source in the immediate project area all reinforce our
    earlier conclusion that the project activities, including
    the driving of piles, will have no significant impact on
    the continuing migration of the contaminants in the
    project area. No modification of the highway project
    should be required.
    R.39, Ex.1040, A.R. at 10079. In a May 2, 2002 memorandum
    from Mr. Fauble of WDNR to Mr. Wade of WDOT, Mr.
    Fauble stated that, per Mr. Wade’s request, he had reviewed
    the initial monitoring data and that none of the data contra-
    dict his and Mr. Czarkowski’s August 22, 2000 memo.
    Specifically, he noted that TCE levels were well below state
    enforcement standards, there were no detects of arsenic, and
    there were very low VOC detects.
    Construction began on the Project in May of 2002, in-
    cluding the insertion of the pilings. On May 15, 2002, the
    U.S. EPA sent a letter to U.S. Senator Russ Feingold of
    Wisconsin concluding that the “U.S. EPA has determined
    that the Ackerville project will not significantly impact
    groundwater quality.” A.R. at 10474-10475. On June 25,
    2002, the U.S. EPA sent “a follow-up letter” to a June 5, 2002
    meeting that included Mr. Gonyo, other citizens and U.S.
    EPA staff. The letter noted that EPA staff “confirmed and
    reiterated” its position in the June 5th meeting that the “U.S.
    EPA does not believe that the Ackerville project will
    significantly alter long-term groundwater quality in this
    area,” and the letter also stated the agency does not believe
    22                                                No. 03-2644
    sufficient reason exists to change its position. R.48 at 2.
    By the time Citizens filed this lawsuit on July 3, 2002, 150
    of the 177 pilings (84%) necessary for the Project already
    had been inserted. On November 21, 2002, Mr. Bauman of
    WDOT sent a memorandum with the new monitoring well
    results. R.39, Ex.1046 at 1. The memo noted that TCE levels
    were well below detectable limits, arsenic levels had
    increased in two wells but were well below the DNR
    Prevention Action Limit, and that WDOT continued to
    believe the Project would not have a significant effect on the
    groundwater in Ackerville. 
    Id. 2
    .   County J/Highway 164 Project (Project # 2748-01-01)
    On April 9, 2001, a final Environmental Impact Statement
    (“EIS”) was approved by the FHWA for the County
    J/Highway 164 Project for distribution to agencies and the
    public. On March 6, 2002, the FHWA adopted the selected
    alternative that was set forth in the EIS for “WisDOT Project
    I.D. 2748-01-01.” R.39, Ex.1045 at 12. This alternative
    “widen[s] County J/WIS 164 on its present alignment, and
    incorporates the existing roadway as part of the ultimate
    4-lane facility.” 
    Id.
     at VI. The Project extends for approxi-
    mately 18 miles and abuts the Ackerville Bridge Project at
    its northernmost end. 
    Id.
     at IV. The key objectives for this
    road-widening project include providing for increasing
    traffic demands and addressing safety concerns due to the
    traffic and current inadequacies of the roadway. 
    Id.
     at IV-VI.
    B. District Court Proceedings
    On June 12, 2003, the district court denied Citizens’
    motion for a preliminary injunction and ruled against
    Citizens on the merits. Before turning to the merits, the
    district court determined that the standing requirement was
    satisfied by at least some of Citizens’ individual members,
    No. 03-2644                                                 23
    as well as the association itself. It also held that Citizens’
    claims were not moot or barred by the doctrine of laches
    because Citizens had filed after 150 of the 177 pilings (84%)
    necessary for the Ackerville Bridge Project were already in
    the ground. Both of these issues were thoroughly and
    correctly analyzed by the district court, and we shall not
    further discuss them.
    As to the merits, the district court first determined that,
    overall, the defendants had taken the requisite “hard look”
    at the environmental consequences of the Project. Second,
    the court held that the defendants had considered suffi-
    ciently reasonable alternatives and had “made a fully
    informed decision to proceed with the alternative involving
    the overpass structure.” R.52 at 54. Finally, the court de-
    termined that the defendants made a “reasonable decision
    in establishing the project termini” and that the Ackerville
    Bridge Project had not been improperly segmented from the
    County J/Highway 164 Project.

    DISCUSSION
    A. “Hard Look” at Environmental Consequences
    This court’s review of agency action under NEPA is
    governed by the APA. See Indiana Forest Alliance, Inc. v.
    United States Forest Serv., 
    325 F.3d 851
    , 858 (7th Cir. 2003).
    The APA instructs courts to set aside agency action only if
    it is “arbitrary, capricious, an abuse of discretion, or other-
    wise not in accordance with the law.” 
    5 U.S.C. § 706
    (2)(A).
    Under this standard, our inquiry is “searching and careful”
    but “the ultimate standard of review is a narrow one.”
    Marsh v. Oregon Natural Res. Council, 
    490 U.S. 360
    , 378 (1989)
    (internal quotations and citations omitted). We only must
    24                                                No. 03-2644
    ask “whether the decision was based on a consideration of
    the relevant factors and whether there has been a clear error
    of judgment.” 
    Id.
     “If an agency considers the proper factors
    and makes a factual determination on whether the environ-
    mental impacts are significant or not, that decision im-
    plicates substantial agency expertise and is entitled to
    deference.” Indiana Forest Alliance, 
    325 F.3d at 859
    . In the
    context of NEPA, arbitrary and capricious review prohibits
    a court from “substitut[ing] its judgment for that of the
    agency as to the environmental consequences of its actions.”
    Kleppe v. Sierra Club, 
    427 U.S. 390
    , 410 n.21 (1976). In fact,
    “[t]he only role” for a court in applying the arbitrary and
    capricious standard in the NEPA context “is to insure that
    the agency has taken a ‘hard look’ at environmental conse-
    quences.” 
    Id.
    NEPA sets forth a broad national commitment to pro-
    tecting and promoting the environment. See Robertson v.
    Methow Valley Citizens Council, 
    490 U.S. 332
    , 349 (1989). Like
    the APA, NEPA “does not mandate particular results, but
    simply prescribes the necessary process. If the adverse
    environmental effects of the proposed action are adequately
    identified and evaluated, the agency is not constrained by
    NEPA from deciding that other values outweigh the
    environmental costs.” 
    Id.
     (internal citations omitted). One
    process required under NEPA is that all federal agencies
    must prepare an “environmental impact statement” (“EIS”)
    for “major Federal actions significantly affecting the quality
    of the human environment.” 
    42 U.S.C. § 4332
    (2)(C); see also
    Heartwood, Inc. v. United States Forest Serv., 
    230 F.3d 947
    , 949
    (7th Cir. 2000). This report is “a detailed analysis and study
    conducted to determine if, or the extent to which, a particu-
    lar agency action will impact the environment.” Heartwood,
    
    230 F.3d at 949
    .
    In evaluating whether an EIS is necessary, Council on
    No. 03-2644                                                25
    Environmental Quality (“CEQ”) regulations instruct that the
    term “significantly” in the statute requires consideration of
    both “context” and “intensity.” 
    40 C.F.R. § 1508.27
    (a)-(b).
    Intensity in turn requires agencies to consider, among other
    factors, “the degree to which the proposed action affects
    public health and safety”; “the degree to which the effects
    on the quality of the human environment are likely to be
    highly controversial”; and “the degree to which the possible
    effects on the human environment are highly uncertain or
    involve unique or unknown risks.” 
    Id.
     § 1508.27(b)(2), (4),
    (5).
    These considerations are often spelled out in the pre-
    liminary stages of a proposed project in an environmental
    assessment (“EA”). An EA is a shorter, rough-cut, low-
    budget EIS which is mandated when, as here, proposed
    action is neither one normally requiring an EIS nor one
    categorically excluded from the EIS process. See 
    40 C.F.R. § 1508.9
    ; 
    23 C.F.R. § 771.115
    (c); Indiana Forest Alliance, 
    325 F.3d at 856
    . Among other information, it “provide[s]
    evidence and analysis that establish[es] whether or not an
    EIS or a Finding of No Significant Impact (’FONSI’) should
    be prepared.” 
    40 C.F.R. § 1508.9
    (a)(1); see also Rhodes v.
    Johnson, 
    153 F.3d 785
    , 788 (7th Cir. 1998).
    In this case, Citizens alleges that the defendants failed to
    take a “hard look” at the environmental consequences of the
    Ackerville Bridge Project and that an EIS is required for the
    Project under NEPA and its implementing regulations. In
    assessing these contentions, we must, as a threshold matter,
    state with precision the question at issue. Both parties agree
    there are contaminants in the groundwater in the general
    vicinity of the Ackerville Bridge Project. They disagree as to
    the source of the contaminants and the extent of the threat
    posed by the contaminants. Citizens claims the source is the
    Waste Management landfill. The defendants are not sure
    26                                                     No. 03-2644
    what the precise source is. Citizens claims the levels of con-
    taminants are unsafe. The defendants believe they are not.
    Regardless of the source and extent of the contaminants, the
    key question is whether there is a nexus between the
    Ackerville Bridge Project, which the defendants are imple-
    menting and which NEPA and its regulations govern, and
    the preexisting contamination in the general vicinity, which,
    apart from the Project, NEPA and its regulations do not
    affect.
    In this action, the only possible mechanism by which
    Citizens claims the Project will exacerbate this preexisting
    condition is through the bridge pilings. In their view, when
    driven into the groundwater, the pilings will create a zone
    of permeability that will allow the contaminants to flow to
    the private drinking water of Ackerville citizens. Thus, the
    narrow question before us is whether the pilings needed for
    the bridge will advance or exacerbate the migration of
    contaminated water toward private wells in the Ackerville
    area.3
    3
    Citizens puts a great deal of emphasis in its argument on the
    allegation that the defendants did not adequately determine the
    source and extent of the contamination, especially the extent of
    arsenic, before proceeding with a finding of no significant impact
    and with construction. See, e.g., Appellant’s Br. at 28, 31-32, 36-37.
    As a threshold matter, we note that the defendants did explore
    the levels of contamination both before and after the April 2000
    EA/FONSI enough to determine that there was preexisting
    contamination, at least in small amounts, and to determine that
    the Project itself did not threaten to exacerbate the contamination
    without some mechanism to advance it toward the Ackerville
    drinking water. See R.38, Ex.1003, A.R. at 00002; R.38, Ex.1015,
    A.R. at 00714; R.38, Ex.1020, A.R. at 12295. Nevertheless, Citizens’
    argument misses the point. Again, we emphasize that the
    (continued...)
    No. 03-2644                                                         27
    Citizens, through its expert, Mr. Thresher, claim that “the
    coarse grains along the boundaries of the driven pilings
    would rotate due to the shearing thereby increasing the
    porosity, and consequently the permeability, of the sands
    and gravels near the pilings.” Appellant’s Br. at 34. This is
    the principle of dilatancy, and in this case, it means the
    driving of pilings will create a zone of permeability (a space
    that chemicals can pass through) around the outside of the
    pilings that would allow contamination from lower levels to
    migrate upward and eventually into private drinking wells
    and water. 
    Id.
     Defendants through their experts at the
    WDNR disagree and instead believe that the “relatively
    small increase in vertical groundwater movement which
    3
    (...continued)
    defendants’ liability under NEPA and its implementing reg-
    ulations rests on a nexus between their Project and the preexist-
    ing contamination. If the Project has no significant effect on the
    contamination, the contamination is still a problem, but it is a
    problem that does not fall under the jurisdiction of the FHWA
    and WDOT. Rather, it falls under the U.S. EPA and WDNR which
    are charged with maintaining the quality of groundwater for our
    citizens. In fact, both in relation to and apart from this Project, the
    U.S. EPA and WDNR have been monitoring the contamination
    and its effect on the groundwater in Ackerville for some time. See
    R.38, Ex.1024, A.R. at 10164-10165; A.R. at 10476-10477.
    In sum, NEPA requires agencies to take a “hard look” at the
    environmental consequences of their projects. Kleppe v. Sierra Club,
    
    427 U.S. 390
    , 410 n.21 (1976). If an agency’s project does not itself
    “significantly” affect the environment, then neither NEPA nor its
    implementing regulations require an agency to perform an EIS or
    to remedy a preexisting environmental problem merely because
    the project happens to take place in the vicinity of that preexisting
    environmental problem. See 
    42 U.S.C. § 4332
    (2)(C); 
    40 C.F.R. § 1508
     (discussing “effects” which “are caused by the action”)
    (emphasis added).

    might be expected along open spaces surrounding even
    several dozen pilings is insignificant compared to the
    quantity of natural vertical movement.” R.38, Ex.1020, A.R.
    at 12295. Again, we emphasize that we do not approach this
    dispute as a panel of environmental experts attempting to
    decide which party is correct. We only review whether the
    agencies charged with carrying out this project took a “hard
    look” at the relevant information and consequences and
    made an informed judgment.
    The April 2000 EA/FONSI for the Ackerville Bridge
    Project does not contain a specific discussion of the effects
    of the pilings. Rather, it discusses the required excavation,
    noting it will not reach the groundwater, and concludes:
    “The Department has determined that the potential for
    encountering and impacting hazardous materials during
    construction of this project does not exist. Therefore, there
    is no purpose or need for preparation of an EIS.” R.38,
    Ex.1003, A.R. at 00005. Other contemporaneous documents
    do contain general conclusions that the pilings will have no
    effect on the contamination. For example, the Addendum to
    the Phase 1 Report, also released in April of 2000, states
    without elaboration that it is “unlikely the pilings for the
    structure supports . . . will cause an impact on plume
    movement or concentrations.” R.38, Ex.1015, A.R. at 00714.
    Likewise, Mr. Wade, a Hazardous Materials Engineer for
    WDOT, concluded in a March 14, 2000 letter that “it is also
    unlikely that project pilings or water detention/infiltration
    basins will cause an impact on plume movement or con-
    centrations.” R.38, Ex.1009, A.R. at 00728. Although based
    on the evidence in the record, we believe the defendants
    knew the pilings would extend into the groundwater when
    No. 03-2644                                                        29
    the April 2000 EA/FONSI was issued,4 there is no “hard
    4
    The first, official, public acknowledgment that the pilings
    would extend into the groundwater was an EMCS report dated
    February 26, 2001. However, the defendants explain that they had
    assumed before the issuance of the April 2000 EA/FONSI that the
    pilings would extend below the groundwater, and though
    ambiguous, the most plausible inference from the record is that
    they in fact made that assumption. For example, the defendants
    asked the question in a “Fact Sheet/Topics of Concern” dated
    February 15, 2000: “If there is contamination in the shallow
    groundwater, couldn’t the structure pilings create a ‘channel’ to
    contaminate [sic] the deep groundwater where our drinking
    water comes from?” R.38, Ex.1008, A.R. at 00146. In a March 24,
    2000 letter from Ken Wade of WDOT to EMCS, Mr. Wade stated:
    The water table for this region is approximately 30 feet below
    the ground surface. If construction plans for the footings
    require only 4 to 5 feet of excavation, it is very unlikely that
    contaminated groundwater will impact the project.
    It is also unlikely that project pilings . . . will cause an impact
    on plume movement or concentrations.
    R.38, Ex.1009, A.R. at 00728 (emphasis added). This language is
    mirrored in the April 2000 Addendum. R.38, Ex.1015, A.R. at
    00714. Furthermore, just months after the issuance of the April
    2000 EA/FONSI, Mr. Gonyo wrote a letter to the FHWA re-
    questing reconsideration of the FONSI, and this letter stated:
    “[T]he pilings will have to be driven into and below the contami-
    nated groundwater table.” R.38, Ex.1017 at 2. Finally, the WDNR
    was involved in this Project well before the issuance of the April
    2000 EA/FONSI, see R.38, Ex.1003, A.R. at 00005 (Basic Sheet 2)
    (discussing “extensive coordination” with the WDNR in finding
    no significant impact), and Mr. Fauble of WDNR later noted in a
    correspondence: “When I first reviewed the environmental con-
    cerns regarding this project as part of the team here at DNR, I
    was aware that pilings would be driven below depths of 30 feet,
    (continued...)

    look” analysis to support the conclusion reached by the
    defendants that the pilings would not have a significant
    effect. Indeed, the defendants appear to acknowledge there
    was not a “hard look” analysis of the effect of the pilings in
    April of 2000; instead, the defendants rely on the post-
    EA/FONSI, August 22, 2000 memo of their experts at
    the WDNR as the basis for their “hard look.” See R.29 at 11
    (defendants’ answers to district court’s questions) (“The
    specific question as to how the pilings would affect ground-
    water and more particularly, the movement of arsenic and
    TCE was fully addressed after the FONSI on a number of
    occasions by various persons.”) (emphasis added); Appel-
    lees’ Br. at 49 (stating that “the timing of the final determi-
    nation of the depth that the pilings would extend into the
    ground is of little relevance based upon the findings the
    WDNR reached in its August 22, 2000, memorandum”).
    After the issuance of the final EA/FONSI, Mr. Gonyo
    requested reconsideration of the defendants’ decision in his
    July 7, 2000 letter to the FHWA. One concern specifically
    raised is that “the pilings will have to be driven into and
    below the contaminated groundwater table.” R.38, Ex.1017
    at 2. The FHWA and WDOT were responsive to Mr.
    Gonyo’s request and solicited the help of the experts at the
    WDNR in reevaluating the Project’s impacts, including the
    effect of driving the pilings into the groundwater table, in
    order to respond to Mr. Gonyo. This exchange resulted in
    the August 22, 2000 WDNR memorandum authored by Mr.
    Czarkowski and Mr. Fauble, which states that “[d]riving
    pilings to depths greater than 30 feet could potentially
    encounter contaminated groundwater.” R.38, Ex.1020, A.R.

    (...continued)
    which is where the groundwater occurs.” R.39, Ex.1031, A.R. at
    13827.
    No. 03-2644                                                 31
    at 12296. However, the memo goes on to conclude that the
    “relatively small increase in vertical groundwater move-
    ment which might be expected along open spaces surround-
    ing even several dozen pilings is insignificant compared to
    the quantity of natural vertical movement.” 
    Id. at 12297
    . As
    required by NEPA, this conclusion was “based on a consid-
    eration of the relevant factors,” Marsh v. Oregon Natural Res.
    Council, 
    490 U.S. 360
    , 378 (1989) (internal quotations and
    citations omitted), specifically, the makeup of the soil into
    which the pilings were to be driven, R.38, Ex.1020, A.R. at
    12296. It also was not “clear error of judgment.” Marsh, 
    490 U.S. at 378
     (internal quotations and citations omitted).
    Finally, the conclusion was arrived at by the defendants’
    experts, on which they were entitled to rely to the exclusion
    of Citizens’ expert. 
    Id.
     (“When specialists express conflicting
    views, an agency must have discretion to rely on the
    reasonable opinions of its own qualified experts even if, as
    an original matter, a court might find contrary views more
    persuasive.”). At this point, the defendants had taken a
    “hard look” and were in full compliance with NEPA and its
    regulations.
    Although we could stop here, we have gone to great
    lengths in reciting the facts to demonstrate that from August
    of 2000 to the beginning of the construction in May of 2002,
    the defendants did not ignore Citizens’ concerns. Rather, the
    defendants attended meetings with state legislators in
    which Citizens’ representatives expressed their concerns,
    responded to Citizens’ various requests for information and
    reconsideration, ultimately agreed to install private moni-
    toring wells to study the contamination despite the belief
    the Project would have no significant impact on the contam-
    ination, and reviewed, and had the WDNR review, the
    results of the initial monitoring from the newly installed
    wells and any effects those results might have on the
    Project. In addressing Citizens’ concerns, the defendants
    32                                                No. 03-2644
    and WDNR also worked with other agencies including the
    U.S. EPA, Wisconsin OCR, and the Wisconsin Department
    of Health and Family Services, all of which confirmed the
    defendants’ conclusion that the Project would not signifi-
    cantly affect the groundwater contamination. To be sure, the
    defendants did not change their position as result of Citi-
    zens’ requests and challenges, but they were not required to
    do so. See Robertson v. Methow Valley Citizens Council, 
    490 U.S. 332
    , 350 (1989) (stating that NEPA “simply prescribes
    the necessary process” but “itself does not mandate particu-
    lar results” (citations omitted)).
    In taking a hard look at the environmental consequences,
    the the defendants also made a reasoned determination that
    an EIS was not required. As noted previously, an EIS is only
    required for “major Federal actions significantly affecting the
    quality of the human environment.” 
    42 U.S.C. § 4332
    (2)(C)
    (emphasis added). According to CEQ regulations, “signifi-
    cantly” requires an agency to consider the “context” and
    “intensity” of a project’s environmental consequences. See
    
    40 C.F.R. § 1508.27
    (a)-(b). Citizens claims the defendants
    failed to consider three factors that CEQ regulations instruct
    agencies to “consider[]” under the intensity prong. See 
    id.
    § 1508.27(b). First, it claims the defendants failed to consider
    “the degree to which the proposed action affects public
    health and safety.” Id. § 1508.27(b)(2). The defendants,
    however, did consider this factor but found the Project, and
    specific to this litigation, the pilings, would have an insig-
    nificant effect. This factor must also be read in the context of
    the regulation’s instruction that agencies consider
    “[i]mpacts that may be both beneficial and adverse.” Id.
    § 1508.27(b)(1). The defendants found not only that the
    negative environmental impacts of the Project were insignif-
    icant, but also that the Ackerville Bridge Project was the best
    way to solve serious safety problems with the current
    roadway facility.
    No. 03-2644                                                   33
    The defendants also did not fail to consider “the degree to
    which the effects on the quality of the human environment
    are likely to be highly controversial.” Id. § 1508.27(b)(4).
    Citizens has met its initial burden of establishing that the
    Project was highly controversial, as we recently defined that
    term in Indiana Forest Alliance, Inc. v. United States Forest
    Service, 
    325 F.3d 851
    , 858 (7th Cir. 2003) (“[T]his factor
    considers whether there is a substantial dispute about the
    size, nature or effect of an action in the relevant commu-
    nity.”). However, that is only the first step in the analysis.
    As we further explained in Indiana Forest Alliance, if the
    plaintiff meets the initial burden,
    the agency must consider the dispute and address the
    concerns in its final decision. This two-step approach
    recognizes that as long as the agency has taken a “hard
    look” at the relevant issues involved in the preparation
    of an EIS and satisfactorily explained its subsequent
    decision, the agency decision should not be set aside.
    
    Id. at 858
    . In this case, the defendants did just that. See R.38,
    Ex.1020, A.R. at 12295-12296; R.38, Ex.1022, A.R. at 06225.
    The mere fact that there is still disagreement or that Citi-
    zens’ expert disagrees with the defendants’ experts does not
    render the defendants out of compliance under this factor.
    See Indiana Forest Alliance, 
    325 F.3d at
    861 (citing multiple
    cases for the proposition that scientific dispute does not
    render an agency’s action arbitrary and capricious).
    Finally, the defendants considered “the degree to which
    the possible effects on the human environment are highly
    uncertain or involve unique or unknown risks.” 
    40 C.F.R. § 1508.27
    (b)(5). Although they acknowledged uncertainty as
    to the source and extent of the threat of the contaminants to the
    Ackerville area, they found with certainty that the Project’s
    effects on the contamination and environment were insignifi-
    cant. That conclusion was informed and reasoned, and thus
    34                                                No. 03-2644
    cannot be second-guessed. See Marsh, 
    490 U.S. at 378
    . In
    summary, we hold that the defendants took a “hard look”
    at the environmental consequences and in doing so, made
    an informed and reasoned determination that no EIS was
    required for the Project.
    Before moving on, we must address one last contention by
    Citizens. Citizens argues that this analysis is faulty because,
    temporally, our “hard look” analysis should extend only to
    April of 2000, when the defendants formally issued the
    EA/FONSI. The defendants did not stop with the issuance
    of the EA/FONSI, however, and we believe neither should
    our analysis. First, we do not believe this runs afoul of the
    administrative record requirement. “[T]he focal point for
    judicial review should be the administrative record already
    in existence, not some new record made initially in the
    reviewing court.” Camp v. Pitts, 
    411 U.S. 138
    , 142 (1973). The
    “hard look” inquiry is focused on “the full administrative
    record that was before the Secretary at the time he made his
    decision.” Citizens to Preserve Overton Park, Inc. v. Volpe, 
    401 U.S. 402
    , 420 (1971) (emphasis added), overruled on other
    grounds by Califano v. Sanders, 
    430 U.S. 99
    , 105 (1977).
    Although the formal “decision” of no significant impact was
    made at the time of the April 2000 EA/FONSI in this case,
    the defendants reconsidered their position pursuant to the
    July 7, 2000 request of Mr. Gonyo. With the analysis of the
    experts at the WDNR, as memorialized in the August 22,
    2000 memo, the defendants took a “hard look” at the
    consequences of the pilings and made a further “decision”
    that the EA/FONSI was valid and thus there was no need
    to withdraw the documents. Mr. Madrzak of the FHWA e-
    mailed Mr. Tufts of the FHWA, the addressee of Mr.
    Gonyo’s request, following completion of the August 22,
    2000 memo: “The DNR note [August 22, 2000 memo]
    confirms the information contained in the revisions to the
    Environmental Assessment. The FONSI remains valid
    No. 03-2644                                               35
    despite Mr. Gonyo’s objections. We will respond accord-
    ingly to his request for FHWA to withdraw approval of the
    FONSI.” R.11, Ex.5 (attached e-mail).
    The purpose of confining judicial review to the admin-
    istrative record is to ensure that agencies adequately eval-
    uate their proposed course of action before they act and do
    not simply attempt to justify rash, uniformed actions
    through “ ‘post hoc’ rationalizations” once they are aware
    they are being sued. Citizens to Preserve Overton Park, 
    401 U.S. at 419
     (quoting Burlington Truck Lines v. United States,
    
    371 U.S. 156
    , 168-69 (1962)). The defendants in this case did
    not begin construction until May of 2002 and were not
    informed they were being sued until about the same time.
    See R.52 at 40-41. Therefore, the documents in the record
    that were developed in the months following the issuance
    of the April 2000 EA/FONSI, including the August 22, 2000
    memo, were analyzed approximately a year and a half
    before the defendants even knew they were being sued and
    took the action, the construction, in dispute. These doc-
    uments establish that in reconsidering the decision to
    release the EA/FONSI, the defendants did indeed take a
    “hard look” at the possibility of increased contamination
    caused by the pilings. This is not the kind of post-hoc
    rationalization the Supreme Court has counseled against
    through the administrative record requirement. See Citizens
    to Preserve Overton Park, 
    401 U.S. at 419
     (discussing the
    invalidity of affidavits prepared for litigation). To now ig-
    nore the analysis in the months subsequent to the formal
    EA/FONSI would not only require us to elevate form over
    substance, but it would also require us to ignore the funda-
    mental purpose of NEPA, to ensure that agencies consider
    the environmental consequences of their actions before they
    act, which was satisfied in this case. See Marsh, 
    490 U.S. at 371
    .

    Beyond the relevant administrative record, our position
    might be criticized for looking past the date on which the
    defendants officially stamped the EA/FONSI because these
    documents are intended to be the culmination of
    an agency’s environmental assessment. Cf. Southwest
    Williamson County Cmty. Ass’n v. Slater, 
    976 F. Supp. 1119
    ,
    1123 (M.D. Tenn. 1997) (finding that the issuance of an EIS
    is a final agency action), aff’d in part and vacated in part, 
    173 F.3d 1033
     (6th Cir. 1999). NEPA and its regulations require
    agencies to take a “hard look” at the “significance” of the
    consequences of their actions before issuing an EA/FONSI,
    see 
    42 U.S.C. § 4332
    (2)(C), but also contemplate the reality
    that, after the formal issuance of an EIS or EA/FONSI, it is
    often the case that new information comes to light or the
    project changes. See Marsh, 
    490 U.S. at 370-84
     (discussing
    what is required of an agency under the regulations when
    a project changes or new information comes to light after
    the formal issuance of an EIS). Here, we have an analogous
    situation. A known issue came into sharper focus after the
    formal environmental documents were issued. The defen-
    dants apparently had considered the effect of driving the
    pilings into and below the groundwater table before the
    April 2000 EA/FONSI, and had concluded that the pilings
    would have no effect on the contamination. However, when
    Mr. Gonyo requested reconsideration of the FONSI, the full
    import of the issue became clear, and the defendants did a
    reevaluation, specifically analyzing the effect of the pilings.
    In this regard, the Supreme Court has instructed that
    “NEPA does require that agencies take a ‘hard look’ at the
    environmental effects of their planned action, even after a
    proposal has received initial approval.” See Marsh, 
    490 U.S. at 374
    . FHWA regulations implementing NEPA accordingly
    require that “[a]fter approval of the . . . FONSI . . ., the
    applicant shall consult with the Administration prior to
    requesting any major approvals or grants to establish
    No. 03-2644                                                   37
    whether or not the approved environmental document . . .
    remains valid for the requested Administration action.” 
    23 C.F.R. § 771.129
    (c). As our analysis above demonstrates, the
    defendants in this case took a “hard look” at the environ-
    mental effects of the Project, specifically, the pilings, in the
    months following the formal issuance of the EA/FONSI,
    and determined the previous EA/FONSI remained valid.
    This action put them in substantial compliance with NEPA.
    Not only are agencies required to reevaluate their original
    documents, but sometimes they are also required to supple-
    ment formally the prior environmental documents. NEPA
    itself does not expressly address post-decision supplements
    to an EA/FONSI, and neither do the implementing regula-
    tions. The regulations do discuss when an EIS must be
    formally supplemented, and the Supreme Court has elabo-
    rated on this requirement. See Marsh, 
    490 U.S. at 370-84
    ; 
    40 C.F.R. § 1502.9
    (c); 
    23 C.F.R. § 771.130
    . Nevertheless, 
    23 C.F.R. § 771.129
    (c), quoted above, necessarily requires that
    an inadequate FONSI be formally supplemented if it no
    longer “remains valid.” 
    Id.
     In this case, the defendants
    determined that the impacts of the pilings were insignificant
    and that the EA/FONSI remained valid; thus, no supple-
    mentation was required. See Marsh, 
    490 U.S. at 385
    (“[H]aving [taken a ‘hard look’ at the proffered evidence]
    and having determined based on careful scientific analysis
    that the new information was of exaggerated importance,
    the Corps acted within the dictates of NEPA in concluding
    that supplementation was unnecessary.”); Price Rd. Neigh-
    borhood Ass’n, Inc. v. United States Dep’t of Trans., 
    113 F.3d 1505
    , 1510 (9th Cir. 1997) (finding supplementation to
    the EA/FONSI unnecessary when the FHWA and Arizona
    Department of Transportation reevaluation revealed there
    were no “discernable” differences in environmental effects
    from the change in the project); Vine Street Concerned
    Citizens, Inc. v. Dole, 
    630 F. Supp. 24
    , 29 (E.D. Pa. 1985) (“The
    38                                                  No. 03-2644
    projected increase in the Expressway traffic is not quantita-
    tively or qualitatively significantly different from what was
    considered in the FEIS”; therefore, no formal supple-
    mentation is required.). Furthermore, we agree with the
    district court that the defendants, in effect, created a de facto
    supplement to the EA, which was the basis of their “deci-
    sion” that the FONSI was still valid. See Lake Region Legal
    Defense Fund, Inc. v. Slater, 
    986 F. Supp. 1169
    , 1196 (N.D.
    Iowa 1997) (finding that although a “formal ‘supplemental
    EA’ has not been prepared in this case,” “the administrative
    record indicates that the defendants have continued to
    review the impacts associated with changed conditions in
    the Highway 71 project”). Finally, we note that to remand
    with an order that the defendants formally supplement the
    EA and republish the FONSI at this late date, when NEPA’s
    letter and spirit have been complied with, when the pilings
    are in the ground, and when the bridge is up, would be
    futile. See Cronin v. United States Dep’t of Agric., 
    919 F.2d 439
    ,
    443 (7th Cir. 1990) (noting that a court need not remand a
    case if doing so would be futile).
    B. Reasonable Alternatives
    NEPA requires that agencies “study, develop, and de-
    scribe appropriate alternatives” to major federal projects. 
    42 U.S.C. § 4332
    (2)(C)(iii) & (2)(E). The inquiry into consider-
    ation of reasonable alternatives is “independent of the
    question of environmental impact statements, and operative
    even if the agency finds no significant environmental
    impact.” River Rd. Alliance, Inc. v. Corps of Eng’rs of United
    States Army, 
    764 F.2d 445
    , 452 (7th Cir. 1985). This does not
    mean, however, that courts should ignore the context in
    which alternatives are considered. When, as here, an agency
    makes an informed decision that the environmental impact
    No. 03-2644                                                 39
    will be small, a view which we are required to accord
    deference, a “less extensive” search is required. 
    Id.
     (“[T]he
    smaller the impact, the less extensive a search for alterna-
    tives can the agency reasonably be required to conduct.”).
    Some courts frame this sliding-scale approach as a “rule of
    reason” inquiry, which governs “both which alternatives the
    agency must discuss, and the extent to which it must discuss
    them.” See Citizens Against Burlington, Inc. v. Busey, 
    938 F.2d 190
    , 195 (D.C. Cir. 1991) (quoting Alaska v. Andrus, 
    580 F.2d 465
    , 475 (D.C. Cir. 1978)). Again, our review is not of the
    agency’s substantive judgment, but of the sufficiency of the
    agency’s consideration of the reasonable alternatives. See
    Methow Valley, 
    490 U.S. at 350
     (“[I]t is now well settled that
    NEPA itself does not mandate particular results, but simply
    prescribes the necessary process.” (citations omitted)).
    We have stated that logically and legally, an agency is
    required to address three questions in considering alter-
    natives. See Simmons v. United States Army Corps of Eng’rs,
    
    120 F.3d 664
    , 668 (7th Cir. 1997). “First, what is the purpose
    of the proposed project (major federal action)? Second,
    given that purpose, what are the reasonable alternatives to
    the project? And third, to what extent should the agency
    explore each particular reasonable alternative?” 
    Id.
    The defendants set forth three purposes for the Ackerville
    Bridge Project. The “primary purpose” is to address safety
    considerations flowing from the layout of the roads and the
    close proximity of the railroads. R.38, Ex.1003, A.R. at 00004.
    Another purpose is to bring the existing facility into compli-
    ance with State Trunk Highway standards, which govern
    the necessary requirements for a road to support truck
    traffic. Id. at 00013. A “secondary purpose” is to provide for
    future expansion of the roadways due to increasing traffic
    in the region. Id. at 00004.
    Given these three purposes, we hold the defendants
    40                                              No. 03-2644
    considered a sufficient number of reasonable alternatives
    and explored them to the extent necessary for this Project.
    See Simmons, 
    120 F.3d at 668
    . In its “Summary of the alterna-
    tives considered” in the EA/FONSI, the defendants first
    considered a “No Action” alternative, under which no
    action would be taken other than routine maintenance. R.38,
    Ex.1003, A.R. at 00013. However, they concluded this
    alternative did not address any of the concerns with the
    existing roadway facility. The defendants also discussed
    their “Recommended Alternative,” which was eventually
    implemented. 
    Id.
     Finally, they considered four “Other
    Alternatives,” but found them all lacking for various
    reasons, including safety concerns and cost-efficiency. 
    Id.
    The defendants also specifically responded to the alter-
    native Citizens urged, and which Citizens now claims was
    rejected for pretextual reasons. Citizens’ proposal included
    re-aligning the intersection at STH 164 and STH 175 to a
    right angle, reducing the steep hills along STH 164/STH 175
    to a right angle, adding traffic gates at the railroad cross-
    ings, and adding signals at the STH 164/STH 175 intersec-
    tion. Citizens alleges that this option was rejected because
    the defendants’ true primary motive for some time has been
    a “desire to preserve a corridor for a possible future 4-lane
    roadway.” Appellant’s Br. at 42 (quoting A.R. at 00004). This
    purpose is why the defendants opted for building an
    overpass structure instead of opting for its proposal, which
    would adequately address the safety concerns. 
    Id.
    As an initial matter, this view of pretextual motive is not
    supported in the record. The EA/FONSI states:
    The main purpose and immediate need for the STH 175
    to STH 60 project is to correct a safety problem at the
    STH 164/175 intersection, correct a hazardous at-grade
    train crossing on STH 164 by building a bridge to cross
    No. 03-2644                                                41
    over the train tracks and reconstruct the existing 2-land
    roadway to correct a deteriorating pavement situation.
    A secondary focus of the project is to preserve a corri-
    dor for a possible future 4-lane roadway.
    R.38, Ex.1003, A.R. at 00004. This prioritization is confirmed
    in multiple other documents. For example, the defendants
    performed an “Accident Analysis Report,” which analyzes
    the safety concerns necessitating this Project and provides
    ample statistical data on the safety issues. R.38, Ex.1004,
    A.R. at 05409-05415.
    Regardless, the defendants specifically analyzed Citizens’
    proposal and found it lacking with respect to all three
    purposes of the Project:
    Substantial impacts to the town of Ackerville would
    occur by re-aligning either roadway. Adding gates at
    the railroad crossings would not address the fact that
    there are currently long delays due to the amount of
    train traffic here. This will only worsen in the future
    since Wisconsin Central Limited has plans to double the
    train traffic on these lines. The installation of signals
    does not guarantee safety. The close proximity of the
    railroad tracks to the intersection may cause traffic to
    back-up past the tracks while waiting to clear the
    intersection. This proposal does not address the need
    for the project in regards to state trunk highway stan-
    dards. The 11% grade just north of the intersection,
    inadequate shoulder widths, poor pavement structure,
    and the inadequate stopping sight distances throughout
    the project are all substantial features of this highway
    which are not addressed. Also, the need for future
    expansion to 4 lanes has not been addressed.
    R.38, Ex.1003, A.R. at 00006.
    Given that the environmental impacts of this Project were
    42                                                No. 03-2644
    found by the defendants to be insignificant, the defendants
    satisfied the requirement that they consider reasonable
    alternatives. We are not entitled to second-guess the defen-
    dants’ reasoned and informed determination that the public
    interest, including the public safety, would be better served
    if the preferred alternative were built.
    C. Segmentation
    Segmentation, as the name suggests, addresses an
    agency’s decision on where one project ends and another
    begins. “In order to ensure meaningful evaluation of al-
    ternatives and to avoid commitments to transportation
    improvements before they are fully evaluated,” FHWA
    regulations require that each action evaluated in an EIS or
    FONSI:
    (1) Connect logical termini and be of sufficient length to
    address environmental matters on a broad scope;
    (2) Have independent utility or independent signifi-
    cance, i.e., be usable and be a reasonable expenditure
    even if no additional transportation improvements are
    made; and
    (3) Not restrict consideration of alternatives for other
    reasonably foreseeable transportation improvements.
    
    23 C.F.R. § 771.111
    (f)(1)-(3).
    “Piecemealing” or “segmentation,” which Citizens alleges
    occurred in this case, “allows an agency to avoid the NEPA
    requirement that an EIS be prepared for all major federal
    action with significant environmental impacts by segment-
    ing an overall plan into smaller parts involving action with
    less significant environmental effects.” City of West Chicago
    v. United States Nuclear Regulatory Comm’n, 
    701 F.2d 632
    , 650
    (7th Cir. 1983). The purpose of segmentation review is not
    No. 03-2644                                                 43
    for a court to decide whether or not an agency drew the
    correct lines when putting the boundaries on its projects.
    Rather, “[s]egmentation analysis functions to weed out
    projects which are pretextually segmented, and for which
    there is no independent reason to exist. When the segmen-
    tation project has no independent justification, no life of its
    own, or is simply illogical when viewed in isolation, the
    segmentation will be held invalid.” Save Barton Creek Ass’n
    v. FHWA, 
    950 F.2d 1129
    , 1139 (5th Cir. 1992) (internal
    quotations and citations omitted). Thus, we are looking for
    agency action that ignored, or gave insufficient weight to,
    the factors set out in the regulations in an attempt to avoid
    the requirements of NEPA.
    Citizens claims the County J/Highway 164 Project was
    impermissibly segmented from the Ackerville Bridge Project
    to allow the defendants to avoid performing an EIS on the
    Ackerville Bridge Project. The County J/Highway 164
    Project is 18.1 miles and its northernmost point abuts the
    Ackerville Bridge Project, which is 1.3 miles. Thus, Citizens
    asserts, of the 19.4 miles of the highway being worked on,
    only 1.3 miles will not be the subject of an EIS, and this 1.3
    miles includes the contamination plume. Furthermore,
    Citizens submits that the “logical terminus is Hwy. 60, not
    an artificial part on a hilltop 1.3 miles south of Hwy. 60.”
    Appellant’s Br. at 43.
    We agree with the district court that these arguments are
    not persuasive. In the EA/FONSI, the defendants explicitly
    considered the three criteria for segmentation set out in 
    23 C.F.R. § 771.111
    , and gave a reasoned justification of how
    their segmentation fit each factor. As to logical termini, the
    defendants explained that “[s]ince the need to bridge the
    train tracks is the driving force behind this project,” the
    south termini for the Project was established just beyond the
    bridge touchdown point. The north termini was established
    44                                                  No. 03-2644
    as the STH 60/STH 164 intersection. See R.38, Ex.1003, A.R.
    at 00004. Citizens argues that the Ackerville Bridge Project
    is really just part of the road-widening plan being imple-
    mented by the County J/Highway 164 Project. However, as
    we noted above, we do not find that the record supports the
    contention that the defendants have been pretextually more
    concerned with road-widening than safety. Indeed, as
    constructed, the bridge meets the immediate safety concerns
    at this critical juncture of railroad and vehicular traffic. It
    would be compatible with the roadway expansion of the
    County J/Highway 164 Project only after modification.
    Furthermore, our review is not to determine whether the
    defendants made the best choice, but only whether they
    made a choice that was informed and reasonable. See Save
    Barton Creek, 
    950 F.2d at 1140
    .
    The second factor, independent utility, is the most im-
    portant factor in highway cases such as this. See 
    id.
     (“In the
    context of a highway within a single metropolitan area, as
    the case at issue—as opposed to projects joining cit-
    ies—courts have focused more on the factor of ‘independent
    utility.’ ” (citations omitted)). With respect to this factor, the
    EA/FONSI pointed out that neither the bridge construction
    project, with its safety focus, or the County J/Highway 164
    Project, with its expansion focus, require the construction of
    any other projects to be usable.
    Finally, as to the third factor, restriction of alternatives,
    the Ackerville Bridge Project contemplates, rather than
    restricts, future roadway projects, including the possibility
    of a four-lane project if found to be needed. See R.38,
    Ex.1003, A.R. at 00004. Indeed, making space for future
    expansion was a “secondary purpose” for the Project in the
    first place.
    In sum, the defendants analyzed the relevant factors set
    out in 
    23 C.F.R. § 771.111
    (f)(1)-(3), and came to a reasoned
    No. 03-2644                                            45
    conclusion. There is also no real evidence to support
    pretextual motive. Accordingly, we hold there was no
    improper segmentation in this case. See Save Barton Creek,
    
    950 F.2d at 1139
    .
    Conclusion
    For the foregoing reasons, we affirm the judgment of the
    district court.
