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. Completed in 1903, it was the longest suspension bridge span in the world until 1924.
The bridge is one of four toll-free vehicular bridges connecting Manhattan Island and Long Island. The others are the Queensboro Bridge to the north, and the Manhattan and Brooklyn Bridges to the south. The Williamsburg Bridge once carried New York State Route 27A and was planned to carry Interstate 78, though the planned I-78 designation was aborted by the cancellation of the Lower Manhattan Expressway and Bushwick Expressway.
