Pennsylvania Avenue Line (Washington, D.C.)

The Pennsylvania Avenue Line, designated as Pennsylvania Avenue on Route D10, and Pennsylvania Avenue Limited on Route D1X, are daily Metrobus routes in Washington, D.C., Operating between the Southern Avenue station (D10) or Naylor Road station (D1X) of the Green Line of the Washington Metro and the Kennedy Center (D10) or Federal Triangle (D1X). Late night D10 trips are truncated to Foggy Bottom station of the Blue, Orange and Silver Lines of the Washington Metro. Until the 1960s, it was a streetcar line, opened in 1862 by the Washington and Georgetown Railroad as the first line in the city.

The routing also incorporated portions of the Naylor Road Line, formerly a standalone route.

Current route

Route D10 begins at the Kennedy Center near the Foggy Bottom–GWU station and follows H and I Streets to Pennsylvania Avenue. Route D1X starts at Federal Triangle and follows 7th Street NW, and Independence Avenue SW, with both routes meeting at the intersection of Independence Avenue and 4th Street Southwest. Both buses routes travel across Southeast and over the Sousa Bridge. At L'Enfant Square, both routes separate. Route D10 travels along 25th Street, Naylor Road and Alabama Avenue, while Route D1X continues along Pennsylvania Avenue to Branch Avenue. Route D10 terminates at the Southern Avenue station, just across the Maryland border, while Route D1X terminates at Naylor Road station, also in Maryland. Both stations are served by the Green Line.

Routes D10 and D1X operate seven days a week. Both routes are supplemented by the Wisconsin Avenue Line, operated by Routes D80 and D82, which traverse the same route as the D10 and D1X, but continue north along Wisconsin Avenue to Friendship Heights station.

Both lines operate out of Andrews Federal Center division with late night trips operating out of Shepherd Parkway division. Prior to being moved to Andrews, both lines operated out of Bladensburg, Shepherd Parkway, and Western division at some point.
