U.S. 29

U.S. 29 is poorly signed route through Washington, DC with the exception of the 0.8-mile stint along the Whitehurst Freeway at Georgetown. U.S. 29 enters Washington across the Francis Scott Key Bridge from Rosslyn, Virginia to join the Whitehurst east to the westbound beginning of Interstate 66. There U.S. 29 transitions into K Street east through Washington Circle to 11th Street NW. 11th Street north doubles as U.S. 29 to Rhode Island Avenue NW. A few blocks east of there is the U.S. 29 turn onto 7th Street north to Silver Spring, Maryland. Left-hand turns from Rhode Island Avenue east onto 7th Street north are prohibited however, making U.S. 29 a discontinuous route.

The Whitehurst Freeway opened to traffic on October 8, 1949. It was named after Herbert C. Whitehurst, director of the D.C. highway department, who died a month before the viaduct completion.1 The elevated freeway was rehabilitated over an eight year period ending in August 1998 at a cost of $100 million.2 U.S. 29 followed M Street NW from the Francis Scott Key Bridge east to New Hampshire Avenue prior to its routing along the Whitehurst and K Street. The 1960s alignment took the route north onto 16th Street and Alaska Avenue to the D.C. line.
