after crossing the 14th street bridge, the freeway has a left-side exit allowing access to us 1 (exit 1). the southbound side of i-395 has no access to northbound us 1 here. i-395 crosses potomac park (exit 2) and a second bridge, the francis case memorial bridge over the washington channel. here, the route bends from a generally northeast direction to a due east direction, interchanging (exit 3) with the 9th and 12th street expressways, two tunnels that carry traffic under the national mall. a series of complex interchanges (numbered 4, 5, 6, and 7) provide partial access to maine avenue and c street sw, as well as connections to interstate 695. immediately after i-695, the freeway makes a hard turn to the due north to follow the third street tunnel immediately under union square and just to the west of the united states capitol building. emerging from the tunnel, i-395 follows a depressed roadway (the center leg freeway) that has three more partial interchanges (exits 8, 9, and 10) with local streets before terminating at new york avenue/us 50.
