How much did Washington Metro Silver Line cost to build?
The Silver Line is the Washington Metro line built as the Dulles Corridor Metrorail Project, a 23.1-mile extension with 11 new stations constructed in two phases from East Falls Church through Tysons and Reston to Dulles International Airport and Ashburn, which the Metropolitan Washington Airports Authority says opened in November 2022.
