American Legion Memorial Bridge

The American Legion Memorial Bridge is a road bridge carrying ten lanes of Interstate 495 across the Potomac River between Maryland and Virginia. The structure uses concrete and steel to span the water and handle the flow of vehicles crossing between the two states.

Construction began in the 1950s and the bridge opened in 1962 under the original name Cabin John Bridge. It was renamed American Legion Memorial Bridge in 1969 to honor military veterans.

This bridge stands as a memorial to American Legion veterans, featuring commemorative elements that recognize military service members throughout its structure.

Crossing during rush hours can be slow since many commuters use this main link between the two states. It helps to check traffic conditions before driving, especially if you are traveling during peak times.

The bridge construction was subject to environmental debates because of its proximity to Plummers Island, which contains sensitive wetlands and native forests. This island required planners to carefully design the bridge and any future expansions to protect the local ecology.
