Silver Line is a 23-mile extension of the exiting Metrorail system with new tracks that extend from East Falls Church, through Tysons and Reston and eventually to Washington Dulles International Airport west to Ashburn. Phase II of the Silver Line will bring Metro to Herndon and beyond and is projected to complete in 2018. The Herndon station will be constructed in the median of the Dulles Toll Road and will connect to the town on its north side via a pedestrian bridge.
