South Capitol Street crosses the Anacostia via the Frederick Douglass Memorial Bridge, which is angled on a northwest–southeast line so that the bridge's southwest terminus does not occur on land owned by Joint Base Anacostia–Bolling. A "mixing bowl" of off- and on-ramps provides access to southbound Suitland Parkway, with an adjacent cloverleaf interchange giving access to Firth Sterling Avenue and the Anacostia Washington Metro station as well as northbound Interstate 295. South Capitol Street then follows a winding path along the eastern border of Joint Base Anacostia–Bolling. Deceleration lanes provide access to Malcolm X Avenue SE and the main gates of Joint Base Anacostia–Bolling and Interstate 295 again. South Capitol Street angles south-southeast at Overlook Avenue SW, passing below Interstate 295 and continues winding south-southeast until it reaches Southern Avenue. It is coterminous with Martin Luther King Jr. Avenue SE for a single block between Halley Place SE and 2nd Street SW before winding toward Southern Avenue and the District boundary line.
