American Legion Memorial Bridge, Road bridge connecting Montgomery County Maryland and Fairfax County Virginia across the Potomac River, US
The American Legion Memorial Bridge carries ten traffic lanes of Interstate 495, spanning the Potomac River through a series of concrete and steel structures.
The bridge opened in December 1962 as Cabin John Bridge and received its current name in 1969 during a military ceremony led by Lt. Gen. Lewis Hershey.
This bridge stands as a memorial to American Legion veterans, featuring commemorative elements that recognize military service members throughout its structure.
The bridge serves as the principal crossing point between Maryland and Virginia, handling substantial daily commuter traffic between technology centers in both states.
Environmental discussions surround the bridge expansion project due to its proximity to Plummers Island, which contains sensitive wetlands and native forest ecosystems.
