Southwest (SW or S.W.) is the southwestern quadrant of Washington, D.C., the capital of the United States, and is located south of the National Mall and west of South Capitol Street. It is the smallest quadrant of the city, and contains a small number of named neighborhoods and districts, including Bellevue, Southwest Federal Center, the Southwest Waterfront, Buzzard Point, and the military installation known as Joint Base Anacostia–Bolling.

South Capitol Street is a major street dividing the southeast and southwest quadrants of Washington, D.C., in the United States. It runs south from the United States Capitol to the D.C.–Maryland line, intersecting with Southern Avenue. After it enters Maryland, the street becomes Indian Head Highway (Maryland Route 210) at the Eastover Shopping Center, a terminal or transfer point of many bus routes.
14th Street NW/SW is a street in Northwest and Southwest quadrants of Washington, D.C., located 1.25 miles (2.01 km) west of the U.S. Capitol. It runs from the 14th Street Bridge north to Eastern Avenue.
Northbound U.S. Route 1 runs along 14th Street from the bridge to Constitution Avenue, where it turns east with US 50. US 1 southbound previously used 15th Street NW due to the ban on left turns from westbound Constitution Avenue to 14th Street, but it now uses the Ninth Street Tunnel, five blocks to the east. 14th Street crosses the National Mall and runs near the White House and through the western side of Washington's Logan Circle neighborhood.
Southwest Federal Center is a business district in Southwest Washington, D.C., nearly entirely occupied by offices for various branches of the U.S. Government, including many of the museums of the Smithsonian Institution.
Southwest Federal Center lies between Independence Avenue and the National Mall immediately to the north, the Southeast-Southwest Freeway (Interstate 395) and the Washington Channel to the south, South Capitol Street to the east, and 15th Street SW to the west.
