Washington Boulevard is a road in Arlington County, Virginia. It begins as a highway, connecting the George Washington Memorial Parkway and Arlington Memorial Bridge (into Washington, D.C.) with Interstate 395, running past The Pentagon and Arlington National Cemetery. It then extends north and west from I-395, crossing Columbia Pike, passing alongside Fort Myer, and connecting with Arlington Boulevard. From there, Washington Boulevard continues north as an arterial road and crosses Wilson Boulevard in the Clarendon neighborhood. It continues west, passing just north of Ballston, then crosses Interstate 66 and ends near Falls Church where it joins I-66.
The Washington Metro stations directly along Washington Boulevard are East Falls Church and Clarendon. The Ballston and Virginia Square stations are located two blocks from Washington Boulevard.
Washington Boulevard is part of the Pentagon road network. The portion of Washington Boulevard east and south of Arlington Boulevard was designated State Route 27 when it was transferred to the Virginia Department of Highways on December 17, 1964.
