The Suitland Parkway is a parkway in Washington, D.C., and Prince George's County, Maryland, administered and maintained by the U.S. National Park Service (NPS), National Capital Parks-East. The road has partial controlled access with a combination of interchanges and at-grade intersections, but without property access for neighboring land-owners. Conceived in 1937, it was built during World War II to provide a road connection between military facilities in the Washington, D.C. metropolitan area. It fully opened on December 9, 1944 as the Camp Springs highway, so called because it connected Camp Springs (now Joint Base Andrews) in Prince George's County with Bolling Air Force Base. However one lane of the highway was opened in mid-October 1944.
