New Hampshire Avenue is a diagonal avenue in Washington, D.C., beginning at the Kennedy Center and extending northeast for about 5 miles (8 km) and then continuing into Maryland, where it is designated Maryland Route 650. New Hampshire Avenue is not contiguous. It stops at 15th and W Streets NW, and resumes again on the other side of Columbia Heights at Park Road NW, a few blocks from Georgia Avenue.

New Hampshire Avenue passes through several Washington neighborhoods including Foggy Bottom, Dupont Circle, Petworth and Lamond-Riggs.

In Maryland, New Hampshire Avenue passes the neighborhoods and towns of Chillum, Takoma Park, Carole Highlands, Langley Park and Silver Spring. It eventually feeds into Damascus Road (Maryland Route 108) at Etchison. Many Maryland residents regard New Hampshire Avenue as a convenient access road to Washington's North Capitol Street, a wide road that starts north of the U.S. Capitol and divides the city into its northwest and northeast quadrants.


In 1907, the commissioners of the District of Columbia asked Congress to appropriate funds to extend New Hampshire Avenue northward to the Maryland state line.[1] The northern portion was proposed in 1908.[2]

Rock Creek Church requested that New Hampshire Avenue not be extended in a straight line in order to be more direct to the church.[3] Thomas H. Carter of Montana[4] and Jacob H. Gallinger of New Hampshire submitted the bill to the Senate.[5] The bill passed in late 1908.[6]

In 1911, the commissioners of the District asked Congress to appropriate funds to extend New Hampshire Avenue in a deflected direction, rather than in a straight line, from its end at Buchanan Avenue to the Maryland state line.[7]

The House of Representatives passed the bill,[8][9] and the Senate passed it soon thereafter.[10]
