Progress on the Silver Line: Girders Placed at Horsepen Run Bridge

Dulles Corridor Metrorail Project crews completed the setting of the four girders that will support the Silver Line's Horsepen Run Bridge in the median of the Dulles International Airport Access Highway (DIAAH) just west of the Route 28 overpass on Wednesday, April 8. 

At 133 feet long and 8 1/2 feet high, the four steel girders were transported during day time hours under police escort.
