John Philip Sousa Bridge

The John Philip Sousa Bridge, also known as the Sousa Bridge and the Pennsylvania Avenue Bridge, is a continuous steel plate girder bridge that carries Pennsylvania Avenue SE across the Anacostia River in Washington, D.C., in the United States. The bridge is named for famous United States Marine Band conductor and composer John Philip Sousa, who grew up near the bridge's northwestern terminus.

The first bridge at this location was constructed in 1804, but burned by United States armed forces in 1814 during the War of 1812. It was replaced in 1815, but the bridge burned to the waterline in 1846. The rapid growth of residential developments east of the Anacostia River led to the construction of a narrow, iron girder bridge in 1890.
