Once construction is complete, the hulking structure will allow pedestrians to access the Silver Line station from the north side of the Dulles Toll Road and Dulles Airport Access Highway, according to information provided by the Dulles Metrorail Corridor Project.
The installation took place in the late-night hours of Oct. 13-14.
Construction work on Phase 2 of the Silver Line, which will extend the Metrorail from Reston to Ashburn, was reported earlier this month to be about two-thirds done. The line is expected to be opened to the public in 2020.
