Interstate 395 (I-395) in Washington, D.C., and Virginia is a  spur route of Interstate 95 (I-95) that begins at an interchange with I-95 in Springfield and ends at an interchange with U.S. Route 50  in northwest Washington, D.C. It passes underneath the National Mall near the U.S. Capitol and ends at a junction with U.S. Route 50 (US 50) at New York Avenue, roughly a mile (1.6 km) north of the 3rd Street Tunnel. Despite its proximity to Interstate 395 in Maryland, the route is unrelated and unconnected.
