The Williamsburg Bridge is a suspension bridge in New York City across the East River connecting the Lower East Side of Manhattan at Delancey Street with the Williamsburg neighborhood of Brooklyn at Broadway near the Brooklyn-Queens Expressway (Interstate 278). It once carried New York State Route 27A and was planned to carry Interstate 78, though these plans were aborted by the cancellation of the Lower Manhattan Expressway and Bushwick Expressway.
