Long Bridge, Railway bridge crossing Potomac River in Washington, DC, United States.
The Long Bridge spans the Potomac River with multiple steel truss sections, carrying freight and passenger trains between Washington DC and Virginia daily.
Originally constructed in the late 19th century, the bridge replaced earlier wooden structures and became a critical rail link during the Civil War period.
The bridge represents over a century of American railroad development and serves as a vital connection point for the Northeast Corridor transportation network.
Currently operating at 98 percent capacity during peak hours, the bridge handles approximately 90 trains daily including CSX freight, Amtrak, and Virginia Railway Express services.
The Long Bridge Project will replace the current two-track system with a modern four-track configuration, increasing daily capacity to over 160 trains by 2030.
