Queensboro Bridge

The Queensboro Bridge is a cantilever bridge over the East River in New York City. The bridge is also named the 59th Street Bridge because its end in Manhattan is between 59th and 60th streets. It was finished in 1909. The Queensboro Bridge connects Midtown Manhattan with Long Island City in the borough of Queens. It goes over Roosevelt Island. The bridge is long. The bridge was renamed after New York City mayor Ed Koch in 2011. Its official name is now the Ed Koch Queensboro Bridge. 
To the north is a tramway that travels in the air. This tramway goes from Manhattan to Roosevelt Island. 
From 1909 to 1917, the span of the bridge between Manhattan and Roosevelt Island was the longest cantilever span in North America.
The bridge used to carry elevated trains. It now carries cars. Since 2000, people can walk across the bridge.
The roadway that uses the bridge is numbered New York State Route 25.
