The Long Bridge is a CSXT owned two-track, century-old bridge that spans the Potomac River in Washington, DC. The Long Bridge Project will increase rail traffic capacity, creating a four-track corridor, and constructing approximately 1.8 miles of improvements including seven rail bridges and pedestrian bridges over land and the Potomac River and related railroad infrastructure between Arlington, VA, and Washington, DC.

The Long Bridge Project will construct a new, two-track railroad bridge next to the existing Long Bridge, creating a four-track corridor. A new bike-pedestrian bridge also will be constructed as part of the mitigation to National Park Service (NPS) parkland and will span the Potomac River and George Washington Memorial Parkway, connecting Long Bridge Park directly to East and West Potomac Parks.

Freight and passenger rail operators within the project corridor include Amtrak, Virginia Railway Express (VRE) and CSXT. Annually, up to 1.3 million Amtrak passengers and 4.5 million VRE commuters traverse the current Long Bridge, which operates at 98% capacity during peak hours. The project’s purpose is to create greater railroad capacity between Virginia and the District of Columbia while alleviating the rail congestion caused by the existing two-track Long Bridge.
