Washington Dulles International Airport rail corridor has reached 32% completion

Posted on in News

USA: Construction has reached 32% for Phase 2 of Metro's Silver Line, the $6.5 billion rail line that will eventually connect Washington Dulles International Airport and eastern Loudoun County with Tysons Corner, Arlington, downtown DC and the metropolitan Washington region.

Being built by the Metropolitan Washington Airports Authority, owners of Washington Dulles International and Reagan National airports, the system is one of the largest construction projects in America. Phase 1, including four stations in Tysons Corner and one in Reston, opened in July 2014. Phase 2 includes stations in Reston, Herndon, at Route 28, at Dulles airport, and in eastern Loudoun - at Loudoun Gateway (Route 606) and at Ashburn (Route 772), which will be the end of the Silver Line.

Construction is speeding up all along the Dulles Corridor which basically follows the Dulles Airport Access Highway/Dulles Toll Road path, swings off into the airport, and then follows the Dulles Greenway to Ashburn.

At Dulles Airport where the tracks are aerial, many of the piers and guideways (bridges) to support those tracks are in place, and pouring decks for trackbeds is almost 50% complete.

The Dulles Airport Station excavations and foundations are done along the face of the parking garage facing the main terminal, steel and precast work continues and the transformation on an existing tunnel beneath the parking bowl into a connection via moving sidewalks from the station to the terminal is taking place.

Construction should be complete in 2019 with the operation date set for 2020. After the construction and testing of the line will be completed, MWAA will turn the project over to the Washington Metropolitan Area Transit Authority, the entity that will own and operate the rail line and set the opening date.
