Introduction(HOV) policies, high-occupancy/toll (HOT) policies, congestion pricing, managed lanes, activetraffic management, and bicycle and pedestrian corridor access. By using a broad approach,the I-66 Multimodal Study focused on identifying and analyzing effective options forimproving mobility along the corridor.Corridor DescriptionThe initial study area for the I-66 Multimodal Study was defined as bounded by the PotomacRiver to the east, Columbia Pike (VA Route 244) to the south, I-495 to the west, and DolleyMadison Boulevard/Chain Bridge Road (VA Route 123) to the north, with a study focus on theI-66 corridor from the Capital Beltway (I-495) east to the Theodore Roosevelt Bridge border.The study area was refined to have a primary focus on the I-66 facility and nearby parallelfacilities, including U.S. Route 29 (Lee Highway), U.S. Route 50 (Arlington Boulevard), andWashington Boulevard (VA Route 237) (see Section 2.0 of the Interim Report).The I-66 corridor includes a complex mix of transportation facilities and services. Inside theBeltway, I-66 itself has two through lanes in each direction. All lanes on I-66 in the peak directionduring the peak period (inbound in the morning, between 6:30 a.m. and 9:00 a.m.; outboundin the evening, between 4:00 p.m. and 6:30 p.m.) are designated as HOV only (with someauthorized exceptions). The study corridor includes parallel arterials that serve non-HOV travelduring the peak periods when single-occupancy vehicles are restricted from using I-66 inthe peak direction. Mass transit within the corridor includes the Metrorail Orange Line (andfuture Silver Line) as well as local and express bus services. The corridor also includes a networkof on- and off-road bicycle facilities.Transit services in the corridor include the Metrorail Orange Line, which currently serves locationsin the corridor, with stations at Rosslyn, Court House, Clarendon, Virginia Square-GMU,Ballston-MU, East Falls Church, and West Falls Church-VT/UVA. Upon completion of Phase Iand Phase II of the Metrorail Silver Line as called for in the CLRP, there also will be directMetrorail service serving Tysons Corner, Reston, Herndon, Dulles Airport, and LoudounCounty. A number of transit operators provide local and express bus services in the corridor.These include the Potomac and Rappahannock Transportation Commission (PRTC), ArlingtonTransit (ART), WMATA Metrobus, Loudoun County Commuter Bus, and Fairfax Connector.Bicyclists and pedestrians also can travel along the I-66 corridor using two primary off-roadroutes – the Washington & Old Dominion (W&OD) Trail and the Custis Trail. The W&ODTrail starts in Purcellville, Virginia and extends to Shirlington, Virginia. The Custis Trail intersectsthe W&OD Trail in Bon Air Park in western Arlington County and parallels I-66 to theeastern edge of Arlington County at the intersection of Lynn Street and Lee Highway, at theVirginia entrance to the Key Bridge. In addition to the bicycle travel facilities, there are fourCapital Bikeshare locations in the study area, located towards the eastern end of the Rosslyn-Ballston Corridor.With these considerations in mind, the I-66 Multimodal Study identified potential mobilityenhancements to alleviate current and projected future congestion within the study area. Theidentified combinations of multimodal improvements could have a significant impact onmobility when compared with the baseline projections for the study year, 2040.1-2 I-66 Multimodal Study
Introduction1.2 Oversight and CoordinationThe lead agencies for this study were VDOT and DRPT. The technical and administrative workconducted for this study was managed and led by Cambridge Systematics, Inc. (CS), with supportfrom a team of subconsultants. The KFH Group, Inc. provided transit expertise; MCVAssociates, Inc. performed data collection; Rummel, Klepper & Kahl, LLP (RK&K) providedtechnical analysis of the highway mobility needs; Sharp & Company, Inc. supported the publicinformation activities; the Southeastern Institute of Research, Inc. (SIR) led the market research;and Toole Design Group LLC provided bicycle and pedestrian expertise.To ensure that the study used a broad lens to evaluate options, the lead agencies formed aParticipating Agency Representative Committee (PARC). The PARC met with VDOT, DRPT,and the project consulting team on a monthly basis to provide input on draft materials andadvise the study. In addition, representatives served as liaisons with their respective agenciesand elected officials and helped to distribute study information to constituents and interestedcitizens. The member agencies of the PARC committee are listed in Table 1.1.Table 1.1 PARC Member AgenciesAgencyArlington CountyCity of AlexandriaCity of FairfaxCity of Falls ChurchDistrict Department of Transportation (DDOT)Fairfax CountyFederal Highway Administration (FHWA)Federal Transit Administration (FTA)Loudoun CountyMetropolitan Washington Council of Governments (MWCOG)Northern Virginia Transportation Commission (NVTC)Potomac and Rappahannock Transportation Commission (PRTC)Prince William CountyTown of ViennaVirginia Railway Express (VRE)Washington Metropolitan Area Transit Authority (WMATA)I-66 Multimodal Study 1-3
