Verrazano-Narrows Bridge in New York: One of the longest suspension bridges in the world, connects boroughs of Staten Island and Brooklyn

The Verrazano-Narrows Bridge in New York is one of the longest suspension bridges in the world, connecting the boroughs of Staten Island and Brooklyn. With a total length of 4,176 meters (13,700 feet) and a span between its towers of 1,298 meters (4,260 feet), it held the record for the longest central span of any suspension bridge in the world when it opened in 1964.

Designed by engineer Othmar Ammann, the bridge is named after Giovanni da Verrazzano, the first known European explorer to sail into New York Bay in 1524. The Verrazano-Narrows Bridge is a vital part of the city’s infrastructure, facilitating transportation between Staten Island and the rest of New York, and enhancing regional connectivity.

Key Facts and Features

Dimensions and Record-Breaking Design

  • Total Length: 4,176 meters (13,700 feet), making it one of the longest suspension bridges globally.
  • Main Span: At 1,298 meters (4,260 feet) between its towers, it held the title of the longest central span in the world from its completion in 1964 until 1981.
  • Tower Height: The two towers rise 211 meters (693 feet) above the water, spaced so far apart that the curvature of the Earth had to be accounted for in their design.

Naming and Historical Context

  • Giovanni da Verrazzano: The bridge honors the Italian explorer who became the first European to sail into New York Bay in 1524.
  • Construction Timeline: The bridge was completed in two phases—its upper deck opened on November 21, 1964, while the lower deck followed in 1969 to accommodate increasing traffic.
