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). Completed in 1903, it was the longest suspension bridge span in the world until 1924.

The Williamsburg Bridge was a big deal when it opened in 1903. It was the longest suspension bridge in the world and the only one to employ all steel towers. It was also one of the last to have special lanes for horses and carriages. The design is said to have been inspired by the Eiffel Tower.

The Williamsburg Bridge is in a busy location connecting South Williamsburg to the Lower East Side of Manhattan. Historically, locals cross it mostly by taking the J, M or Z trains, in a taxi or subway.
