Baltimore-Washington National Parkway

The Baltimore–Washington Parkway (also referred to as the B–W Parkway) is a highway in the U.S. state of Maryland, running southwest from Baltimore to Washington, D.C. The road begins at an interchange with U.S. Route 50 and Maryland Route 201 near Cheverly in Prince George's County at the D.C. border, and continues northeast as a parkway maintained by the National Park Service (NPS) to Maryland Route 175 near Fort Meade, serving many federal institutions.

This portion of the parkway is dedicated to Gladys Noon Spellman, a representative of Maryland's 5th congressional district, and has the hidden Maryland Route 295 designation. Commercial vehicles, including trucks, are prohibited within this stretch. After leaving park service boundaries the highway is maintained by the state and signed with the MD 295 designation. This section of the parkway passes near Baltimore–Washington International Thurgood Marshall Airport. Upon entering Baltimore, the Baltimore Department of Transportation takes over maintenance of the road and it continues north to an interchange with I-95. Here, the Baltimore–Washington Parkway ends and MD 295 continues north unsigned on Russell Street, which carries the route north into downtown Baltimore. In downtown Baltimore, MD 295 follows Paca Street northbound and Greene Street southbound before ending at U.S. Route 40.
