Independence Avenue is a major east-west street in the southwest and southeast quadrants of the city of Washington, D.C., in the United States, running just south of the United States Capitol. Originally named South B Street, Independence Avenue SW was constructed between 1791 and 1823. Independence Avenue SE was constructed in pieces as residential development occurred east of the United States Capitol and east of the Anacostia River. Independence Avenue SW received its current name after Congress renamed the street in legislation approved on April 13, 1934. Independence Avenue SW originally had its western terminus at 14th Street SW, but was extended west to Ohio Drive SW in 1941 and 1942. The government of the District of Columbia renamed the portion of the road in the southeast quadrant of the city (west of the Anacostia River) in 1950.HistoryIn the District of Columbia's Cartesian-coordinate-based street-naming system, Independence Avenue was originally known as South B Street. The street began construction sometime after 1791. By October 1803, it existed definitively between New Jersey Avenue and 1st Street East, and in 1809 it was opened between New Jersey Avenue and Pennsylvania Avenue. By 1816, the entire length of the avenue appears to have been opened. At the time, South B Street's western terminus was on the shore of the Potomac River, which at the time was located where 14th Street NW is now.
