The Long Bridge is a crucial rail bridge between Arlington, VA, and Washington, D.C. It carries nearly 80 CSX Transportation, Amtrak and Virginia Railway Express trains daily and missions of passengers annually. It currently operates at 98% capacity during peak times.
To double rail capacity and improve service in the corridor, the Virginia Passenger Rail Authority (VPRA) has initiated a $2.3 billion program to add a new two-track railroad bridge parallel to the existing Long Bridge. The new structure will also create a bicycle and pedestrian bridge connecting Arlington’s Long Bridge Park and the Mount Vernon Trail to East and West Potomac parks in D.C.
STV is partnering with Trumbull, Fay, S&B, USA Construction and Wagman to form the Long Bridge Rail Partners design-build team. As lead designer, STV will oversee comprehensive civil, structural, environmental and geotechnical engineering along with signals, utilities and landscape architecture design for the program’s South Package – which is focused on the Virginia side of the bridge.
