Long Bridge Project

Long Bridge Study
The District Department of Transportation (DDOT) in coordination with the Federal Railroad Administration (FRA) is completing an Environmental Impact Study on the Long Bridge, a two-track railroad bridge that was constructed in 1904. The Long Bridge, owned by CSX Transportation, Inc. (CSXT), carries traffic from three operators: CSXT, Amtrak and the Virginia Railway Express (VRE). The bridge, which crosses the Potomac River, is the only railroad bridge that connects the District of Columbia and the Commonwealth of Virginia. 
The purpose of the proposed action is to provide additional long-term railroad capacity and to improve the reliability of railroad service through the Long Bridge Corridor. Currently, there is insufficient capacity, resiliency, and redundancy to accommodate the projected demand in future railroad services. The Proposed Action is needed to address these issues and to ensure the Long Bridge Corridor continues to serve as a critical link connecting the local, regional, and national transportation network.
