SE. The road curves southeast and comes to a full interchange with Alabama Avenue SE, with access to and from the westbound direction of the parkway provided by Irving Street SE. Following this, the parkway heads east into woods. At the bridge that carries Southern Avenue SE over the parkway, the Suitland Parkway enters Prince George's County in Maryland. The road heads northeast into Temple Hills, coming to traffic light with MD 637 north of the Naylor Road station on Washington Metro's Green Line. Left turns are prohibited at the MD 637 intersection. A short distance later, the parkway comes to an interchange with MD 5. Past this interchange, the Suitland Parkway continues east and passes under the Green Line, with the median widening as it continues southeast through woods. The median narrows again as the road comes to an interchange with MD 458 in Suitland near the Suitland station on the Green Line. Past MD 458, the parkway median widens again and the road continues through woodland a short distance to the southwest of the Green Line. The road has an at-grade intersection with Meadowview Drive, which heads south into a residential development, before the subway line passes over the parkway to head south. The Suitland Parkway curves east and the median narrows as the road comes to an interchange with Suitland Road. The road continues east through more woods with nearby development including the incorporated town of Morningside, with the median widening as the road comes to a traffic light with MD 337. It is at this point that southbound MD 337 splits from the westbound Suitland Parkway. The parkway passes under I-95/I-495 without an interchange before northbound MD 337 merges onto the eastbound direction of the parkway via a ramp. At this point, the Suitland Parkway passes to the north of Joint Base Andrews and comes to an interchange that provides access to the north gate of the base. A short distance later, both MD 337 and the Suitland Parkway end at a traffic light with MD 4 in Forestville. Commercial vehicles, such as trucks, are allowed on the Washington, DC portion of the parkway, but must exit at Alabama Ave. Exit list See also References External links , including photo in 1990, at Maryland Historical Trust website Suitland Parkway, from the National Park Service United States federal parkways Roads in Maryland Roads in Prince George's County,
