Flatbush Avenue is a major avenue in the New York City Borough of Brooklyn. It runs from the Manhattan Bridge south-southeastward to Jamaica Bay, where it joins the Marine Parkway–Gil Hodges Memorial Bridge, which connects Brooklyn to the Rockaway Peninsula in Queens. The north end was extended from Fulton Street to the Manhattan Bridge as "Flatbush Avenue Extension".

The Manhattan Bridge is a suspension bridge that crosses the East River in New York City, connecting Lower Manhattan at Canal Street with Downtown Brooklyn at the Flatbush Avenue Extension. Designed by Leon Moisseiff and built by the Phoenix Bridge Company, the bridge has a total length of 6,855 ft (2,089 m). It is one of four toll-free vehicular bridges connecting Manhattan Island to Long Island; the nearby Brooklyn Bridge is just slightly farther west, while the Queensboro and Williamsburg bridges are to the north.
