The Aqueduct Bridge, also called the Alexandria Aqueduct, was a bridge that carried traffic between Georgetown, Washington, D.C., and Rosslyn, Virginia, from 1843 to 1923.
It was built to transport cargo-carrying boats on the Chesapeake and Ohio Canal in Georgetown across the Potomac River to the Alexandria Canal. The same eight piers supported two bridges: a wooden canal bridge and an iron truss bridge carrying a roadway and an electric trolley line. The canal was later topped with a wooden roadway bridge. The bridge was closed in 1923 after the construction of the nearby Key Bridge, and demolished in 1933.
One arched stone abutment on the Georgetown (north) end survives; it is overseen by the National Park Service as an historic site.
