Dulles-Loudoun Metrorail Extension

WMATA is seriously considering a Metrorail extension from the West Falls Church Station (Orange Line) to Dulles Airport and beyond. It would be about 20 miles long, and would branch off of the Vienna line just west of the West Falls Church Station. The line would be built in the median of the Dulles Airport Access Road (DAAR) and the Dulles Greenway. There would be stations at Tysons Corner, Reston, Herndon, Dulles Airport and about six others. The line would extend about six miles past the airport into Loudoun County. The cost would be about $2 billion. No funding or construction schedule has been set. Since Loudoun County is not one of the municipalities in the original WMATA interstate compact, legislative changes will be necessary to bring Loudoun into the compact.

The Dulles Corridor Transportation Major Investment Study (MIS) concluded in June 1996. The following recommendations of the DCTS Policy Committee were approved by the (Virginia) Commonwealth Transportation Board (CTB) in August: Alternative 3, a Metro-like seamless system be provided to connect from West Falls Church Station to Dulles Airport and to Route 772 in Loudoun County.
