18th Street NW

18th Street in the Strivers' Section Historic District

18th Street Northwest is a prominent north–south street thoroughfare in the Northwest quadrant of Washington, D.C.

The "18th Street" roadway was part of the 1791 L'Enfant Plan for Washington by Pierre Charles L'Enfant.

In the present day 18th Street also travels through downtown Washington and the Dupont Circle and Mount Pleasant neighborhoods. It is also one of the main streets in the Adams Morgan neighborhood; the other is Columbia Road.

It passes through the Strivers' Section Historic District in the Dupont Circle neighborhood. Many bars, nightclubs, and restaurants are located on 18th Street in Adams Morgan, and on weekends it is frequently congested with cars and pedestrians, especially at last call.
