South Street is a street in Lower Manhattan, New York City, located immediately adjacent to the East River. It runs from Whitehall Street near the southern tip of Manhattan to Jackson Street near the Williamsburg Bridge. The Franklin D. Roosevelt East River Drive, in an elevated portion known as the South Street Viaduct, runs along the entire length of the street.
The street is noted for the South Street Seaport, south of the Brooklyn Bridge, and is the former site of the Fulton Fish Market, which was located just to the north of the seaport. Knickerbocker Village, a municipal housing project, fronts on South Street between the Brooklyn Bridge and Manhattan Bridge in the "Two Bridges" neighborhood. West of the seaport, South Street is the location of a number of office buildings, including 55 Water Street, and the New York City Police Museum.
