What's Being Done

The Dulles Corridor Metrorail Project is a new 23-mile rail line, extending service from the existing Orange Line at the East Falls Church Station in Arlington County to Route 722/Ryan Road in Loudoun County. Construction of Phase 1 is complete from the Dulles Connector Road/I-66 interchange west to Wiehle Avenue in Reston. Crews installed piers and caissons, station foundations.

East Falls Church to Wiehle Avenue (Reston)

The 11.7-mile Phase 1 was completed in July 2014, extending service from East Falls Church through five new stations – four in Tysons Corner, and one at Wiehle Avenue on the eastern edge of Reston. Click here for a map of the stations, and click here for a video that highlights the stations.

Wiehle Avenue to Route 772 (Ashburn)

The 11.5-mile Phase 2 will include construction of six additional stations, from Wiehle Avenue to Route 772 (Ashburn), serving Reston Town Center, Herndon, Dulles Airport and eastern Loudoun County. When both phases are complete, the new line will provide a one-seat (no transfer) ride from Washington D.C. to Tysons Corner, Reston, Dulles Airport and beyond. Review the Phase II fact sheet.

The Metrorail project is being built by the Metropolitan Washington Airports Authority (MWAA). When completed, it will be turned over to the Washington Metropolitan Area Transit Authority (WMATA) as a major addition to Metro’s 106-mile system.

Project Benefits

The Dulles Corridor Metrorail Project will provide high-quality, high-capacity rail service in the Dulles Corridor - a one-seat ride from stops all along the corridor to downtown Washington, with rail service connections to Washington Dulles International and Ronald Reagan Washington National airports.  Benefits of the new line and its construction include:

  • Expanding access for employees and employers to the entire metro region
  • Providing easy access for residents to a vast array of shopping and entertainment venues
  • Encouraging high-density, transit-oriented development around stations in keeping with local land use plans
  • Offering a viable, dependable alternative to automobile travel
  • Promoting walking, biking and healthy lifestyles

Lane Closures

While much construction will take place behind concrete barriers, lane closures, ramp closures and detours will be necessary. No lane closures occur during rush hours – 5 a.m. to 9:30 a.m. and 3:30 p.m. to 9 p.m. There are no lane closures on holiday weekends.

All businesses and residential communities will remain accessible.
