The Manhattan Bridge is a suspension bridge crossing the East River in New York City, connecting Lower Manhattan with Brooklyn
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). It is one of four toll-free bridges spanning the East River; the other three are the Queensboro Bridge, Williamsburg Bridge, and Brooklyn Bridge.
Strangely, the possible use of suspension chains as an alternative to steel wire was still being debated during the early stages of cobstruction
Construction of the towers started c.1901. Opened to traffic on December 31, 1909. It was designed by Leon Moisseiff and is considered to be the forerunner of modern suspension bridges [basis?]. It was the first suspension bridge to utilize a Warren truss in its design.
The Phoenix Bridge Co were the contractors for the erection of the superstructure and steel fabrication.
An upper-deck roadway on the bridge was installed in 1922.
