[edit] Northbound

U.S. Route 1 and Interstate 395 enter the District of Columbia from Virginia on the 14th Street Bridge. Route 1 traffic exits Route 395 from the left to 14th Street, S.W. After 14th Street crosses the National Mall, Route 1 turns right onto Constitution Avenue. It then turns left onto 6th Street, N.W., and then right onto Rhode Island Avenue. Route 1 continues on Rhode Island Avenue through Northeast Washington and into Maryland.

[edit] Southbound

U.S. Route 1 enters the District of Columbia from Maryland on Rhode Island Avenue. Route 1 turns left onto 6th Street, N.W., then right onto L Street, N.W., and then left onto 9th Street, N.W. It enters the Ninth Street Tunnel and joins Interstate 395, which it follows into Virginia.

[edit] History

When originally designated in 1926, US 1 entered Washington on Bladensburg Road. The old route then continued on Maryland Avenue and turned south on 1st Street, where it then turns left into the U.S. Capitol grounds. US 1 went around the Capitol making its way to Pennsylvania Avenue. The route continues on Pennsylvania Avenue to 14th Street where it turns south. US 1 then left Washington on 14th Street as it does today. By 1946, US 1 entered from the north using Rhode Island Avenue continuing all the way to 14th Street (via Vermont Avenue). It was shifted to its current alignment by 1967.
