Williamsburg Bridge.

The Williamsburg Bridge is one of three suspension crossings of the East River in New York City, between the boroughs of Manhattan and Brooklyn. It extends between the intersection of Delancey and Clinton Streets in Manhattan and the intersection of Broadway and Roebling Streets in Brooklyn, 1.5 miles north of the Brooklyn Bridge.

When it opened in 1903, the Williamsburg Bridge was the longest suspension bridge in the world, with a span of 1,600 feet and a total length of 7,308 feet and the first with all-steel towers. The 310-foot steel towers support four suspension cables, made of parallel wires. The massive stiffening trusses were designed not only to withstand high winds, but also to support two tracks of heavy rail traffic in the middle of the bridge deck.

BTC Scope:

• BTC performed strength evaluation of the strength of the main suspension cables of the iconic suspension bridge, utilizing the BTC method.

• The scope includes evaluation of the remaining service life of the main suspension cables.

• Recommendations for future cable openings, inspection, testing and sampling of wires.
