The Arlington Memorial Bridge, often shortened to Memorial Bridge, is a Neoclassical masonry, steel, and stone arch bridge with a central bascule (or drawbridge) that crosses the Potomac River in Washington, D.C., the capital of the United States. First proposed in 1886, the bridge went unbuilt for decades thanks to political quarrels over whether the bridge should be a memorial, and to whom or what. Traffic problems associated with the dedication of the Tomb of the Unknown Soldier in November 1921 and the desire to build a bridge in time for the bicentennial of the birth of George Washington led to its construction in 1932.
