The Silver Line is a 23.1-mile extension of the Metrorail system in the rapidly growing Northern Virginia Dulles Corridor. This public transportation mega-project extends the existing Metrorail system from the Orange Line in Falls Church through Tysons Corner to Dulles International Airport and beyond the airport to Route 772/Ashburn Station in eastern Loudoun County.  The Metropolitan Washington Airports Authority serves as the owner and builder of the Silver Line, managing the design and construction of Phase 1 and Phase 2, and eventually turning ownership and operation over to the Metropolitan Washington Transit Authority (WMATA).  The Airports Authority constructed the Silver Line in two major phases: Phase 1 (opened in July 2014) extended Metro service to Wiehle Avenue in Reston, and Phase 2 will extend the Silver Line from the current Wiehle Avenue Metrorail Station through Dulles International Airport to Route 772/Ashburn Station. The Airports Authority recently announced that the construction of Phase 2 is substantially complete, which allowed WMATA to begin operational readiness testing and pre-revenue preparations before opening to riders. An official opening date has not been set, but the new phase is expected to open to the public in 2022.

Phase 2 of the Silver Line includes at-grade tracks and five at-grade stations in the median of the Dulles International Airport Access Highway (DIAAH) and Dulles Greenway, an aerial (elevated) trackway and one aerial station at Dulles Airport, and Metro’s largest maintenance and storage yard facility, a 90-acre property located north of Dulles International Airport.  Five new garages have been constructed by Loudoun County and Fairfax County near the stations, providing a total of 8,900 park-and-ride spaces for Metrorail users.  Wayside facilities, including eleven traction power substations (TPSS), six tie-breaker stations (TBS), and various stormwater management (SWM) facilities were constructed along the 12-mile alignment of Phase 2.  Phase 2 was separated into two primary construction packages.  Package A is the mainline design-build contract west of Wiehle Avenue consisting of all six stations, the at-grade and aerial trackways, TPSSs and TBSs, and stormwater management facilities.  Package B is the design-build contract for the Dulles Rail Yard and Maintenance Facility. This presentation will be an overview of the construction of Phase 1 and Phase 2 of the Silver Line.

WHEN: Tuesday, January 18, 2022, 12:00 PM to 1:00 PM.
WHERE: Online webinar.
FEE: Registration (members, non-members, life members, students): $5.
One (1.0) Professional Development Hour (PDH) will be awarded for attendance.
