New York Avenue is one of the diagonal avenues radiating from the White House in Washington, D.C. It is a major east-west route in the city's Northwest and Northeast quadrants and connects downtown with points east and north of the city via Cheverly, Maryland, the John Hanson Highway, and the Baltimore-Washington Parkway.
New York Avenue is U.S. Route 50 through Northeast and into Northwest as far west as 6th Street NW. In addition, it is U.S. Route 1 Alternate from Bladensburg Road NE, to 6th Street NW. The northern terminus of Interstate 395 is at a signaled intersection with New York Avenue and 4th Street NW. At that intersection, traffic from New York Avenue in either direction may turn south onto Interstate 395, but traffic on northbound Interstate 395 may turn only right (east) onto New York Avenue.
At its eastern end, New York Ave. becomes the John Hanson Highway, a freeway.
On the east side of Mount Vernon Square, New York Avenue crosses 7th Street. At Mount Vernon Square, traffic on New York Avenue mixes with traffic on Massachusetts Avenue and K Street. East of Mount Vernon Square, New York Avenue is part of the National Highway System.
While the main line of New York Avenue extends northeast of the White House, the avenue resumes southwest of the White House to run one block between 17th and 18th Streets NW. At 18th Street NW, New York Avenue joins E Street NW, which leads to the E Street Expressway. In L'Enfant's original plan, New York Avenue extended for several more blocks. That one-block segment of New York Avenue is also part of the National Highway System.
Locations of interest on or near New York Avenue include the main entrance of the National Arboretum (including four relocated U.S. Capitol Gateposts), the new D.C. Convention Center, the National Museum of Women in the Arts, The New York Avenue Presbyterian Church, and the Corcoran Gallery of Art.
According to a study released in 2005 by the government of the District of Columbia, five of the ten most crash-prone intersections in the city are along New York Avenue. The most crash-prone intersection in the city is at New York Avenue NE and Bladensburg Road NE.
