Flushing Avenue is an approximately five mile street running through northern Brooklyn and west central Queens beginning at the termination of Nassau Street, on the northern fringe of Fort Greene, Brooklyn, and ending where it merges with Grand Avenue, in Maspeth. It divides the neighborhood of Southside Williamsburg from Clinton Hill and East Williamsburg from Bushwick. After crossing the Queens border, the avenue serves as the dividing line between Ridgewood, Queens and West Maspeth, and terminates in Maspeth. Despite its name, the avenue does not extend to Flushing.
