Dulles Corridor Metrorail Project crews are setting the concrete girders that will support the deck of the Silver Line's aerial guideway through Washington Dulles International Airport. The work began Tuesday, April 21 and will continue through the summer.
The girders are being brought from Chesapeake, Virginia area along 64 west and 95 north to the Capital Beltway, 66 west and 28 north to the Dulles International Airport Access Highway (DIAAH) and arrive at the airport via Rudder Road.
Installation began in the area of Cargo Building 5 and 6 during day time hours and will continue northeast towards the intersection of Rudder Road and Autopilot Drive. Once the girders cross Rudder Road they will continue north along Autopilot Drive. The work in this area is expected to start around mid-May and will take place during night time hours between 9 p.m. and 5 a.m.
As girder installation progresses, heavy equipment will be moved along the alignment. Day and night time lane and road closures are expected to occur to accommodate the two 300 ton cranes that will set the ~200,000 pound beams.
Drivers should be alert to new traffic patterns, signage, and detours on Package Court, Air Freight Lane, Rudder Road, Autopilot Drive and Ariane Way in the upcoming weeks. Police will be present during night time lane and road closures.
Detailed information about specific road closures and detours will be issued during the course of the girder installation.
