Opened in 1954, the parkway is a 29-mile scenic highway that connects Baltimore, Maryland with Washington, D.C. The part of the parkway from Washington, D.C. to Fort Meade,Maryland is managed by the National Park Service.

Although the first concept of Parkway design was envisioned by Pierre L'Enfant in his 18th century plan, the concept of a parkway in Washington, D.C. was not approved until 1902. At that time, Parkways were designed for use by bicyclists and horse-drawn carriages.

There are no tolls or fees for use on the parkway. There are no trucks allowed on the parkway.

The United States Park Police patrol the parkway.
