Virginia’s Commonwealth Transportation Board and the Washington Metropolitan Area Transit Authority Board of Directors have selected Metrorail as the preferred transit alternative for the Dulles Corridor. This 23.1-mile addition to the current Metrorail system will extend from the Metrorail Orange Line (between the East and West Falls Church stations) in Fairfax County through Tysons Corner to Washington Dulles International Airport and beyond the airport to Route 772 in Loudoun County. Taking into account the timing of the availability of Federal and local funding, the Virginia Department of Rail and Public Transportation (DRPT) has proposed to the Federal Transit Administration that this Metrorail extension be built in two phases. Phase 1 will complete the first segment from the Orange Line to Wiehle Avenue in Reston, while Phase 2 will complete the remainder of the extension to Route 772 in Loudoun County. Most of the extension would be constructed in the median of the Dulles Airport Access Road and Dulles Connector Road, but the alignment would also directly serve Tysons Corner and Dulles Airport. The extension would include 11 new Metrorail stations, a new rail yard on Dulles Airport property, and improvements to an existing rail yard at West Falls Church. This alignment was selected because it offers the highest ridership potential with the fewest impacts on residential areas and the natural environment. The new Metrorail line will provide direct service to key business and residential activity centers in Fairfax County and Loudoun County. In addition, it will provide high-quality, high-capacity transit and result in travel-time savings between the corridor and the region’s core. This much needed transit extension will expand the reach of the existing regional rail system, offer a viable alternative to automobile travel, and encourage future transit-oriented development.
