Silver Line (Washington Metro) The 11.7 miles (18.8 km) portion of the Silver Line between its split from the Orange Line and Wiehle–Reston East station is in Fairfax County, Virginia and was constructed as Phase 1 of the Dulles Corridor Metrorail Project.[4] Phase 2 expands the line another 11.5 miles (18.5 km) to Loudoun County via Washington Dulles International Airport and adds six stations to the line. Preliminary construction of Phase 2 began in 2014, with an opening scheduled for sometime in 2020.[4][5][6][7][8] The $6.8 billion project is the largest expansion by route mileage since the inception of Metro in 1976.[9][10]
