Maryland State Highway Administration (SHA) is proposing improvements that would upgrade the existing four-lane section of MD 4 (Pennsylvania Avenue) in Prince George's County, Maryland. SHA's proposal includes lowering the profile of MD 4 and raising the elevation of Suitland Parkway to construct a signalized diamond interchange, at the current MD 4 intersection with Suitland Parkway. Suitland Parkway, which is owned by and under the jurisdiction of the NPS National Capital Parks-East, was constructed in 1944 and is listed on the National Register of Historic Places.
