Project Status

The Dulles Corridor Metrorail Project is a 23-mile extension of Washington’s existing Metrorail System. It is being built in two phases by the Metropolitan Washington Airports Authority (MWAA).

Phase 1 of the new line opened on July 26, 2014, connecting East Falls Church with Tysons Corner and Reston, Virginia’s largest employment centers, with downtown Washington and Largo, Maryland. Known as the Silver Line, the extension is operated by the Metropolitan Washington Area Transit Authority (WMATA).

Preliminary construction for Phase 2 began in 2014. It will run from the eastern edge of Reston west to Washington Dulles International Airport and to Ashburn in eastern Loudoun County.
