The Queensboro Bridge, also known as the 59th Street Bridge – because its Manhattan end is located between 59th and 60th Streets – and officially titled the Ed Koch Queensboro Bridge, is a cantilever bridge over the East River in New York City that was completed in 1909. It connects the neighborhood of Long Island City in the borough of Queens with Manhattan, passing over Roosevelt Island. It carries New York State Route 25 and is the westernmost of the four East River spans that carry a route number: NY 25 terminates at the west (Manhattan) side of the bridge, which once carried NY 24 and NY 25A as well. The bridge is flanked on its northern side by the freestanding Roosevelt Island Tramway. The bridge was, for a long time, simply called the Queensboro Bridge, but in March 2011, the bridge was officially renamed in honor of former New York City mayor Ed Koch.
