The Manhattan Bridge is a suspension bridge that crosses the East River in New York City, connecting Lower Manhattan at Canal Street with Downtown Brooklyn at the Flatbush Avenue Extension. The main span is 1,470 ft (448 m) long, with the suspension cables being 3,224 ft (983 m) long. The bridge's total length is 6,855 ft (2,089 m). This is one of four toll-free bridges spanning the East River; the other three are the Queensboro, Williamsburg, and Brooklyn Bridges.
The bridge opened to traffic on December 31, 1909. It was designed by Leon Moisseiff, and is noted for its innovative design. As the first suspension bridge to employ Josef Melan's deflection theory for the stiffening of its deck, it is considered to be the forerunner of modern suspension bridges and this design served as the model for many of the long-span suspension bridges built in the first half of the twentieth century. The Manhattan Bridge was also the first suspension bridge to utilize a Warren truss in its design....Wikipedia (
