There are two north–south arteries in Washington, D.C. named 7th Street that are differentiated by the quadrants of the city in which they are located.
History
Historically, 7th Street was a main north–south road in Washington, D.C., and the main route for travelers and farmers coming into the city from the north. This is evident in its intersection with Mount Vernon Square, a historically important public space, and the original Central Market, located at the intersection of Seventh, Pennsylvania, and Indiana Avenues. The space occupied by this Central Market is now the Navy Memorial. The corridor from here west along F Street and north along Seventh is the city's historic retail shopping district with its large department stores and specialty stores. Seventh Street forms major intersections at Pennsylvania Avenue, E Street NW, H Street NW, K Street NW, and Massachusetts Avenue.
Continuing north, 7th Street crosses the National Mall, where it becomes 7th Street NW. In this southernmost segment of 7th Street NW, it is the main north–south thoroughfare in Penn Quarter and Chinatown.
A second set of 7th Streets lie in the eastern quadrants of the city, parallel to the western ones, in several discontinuous segments. The longest section begins at M StreetSE, just north of the Washington Navy Yard. It continues north through the neighborhood of Capitol Hill. When 7th Street SE crosses East Capitol Street it becomes 7th Street NE and continues due north, ending at Florida Avenue, just south of Gallaudet University. Shorter segments of the 7th Street SE exist south of the Anacostia River, while parts of 7th Street NE are further north in the Brookland neighborhood.
