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.
No tolls are charged for motor vehicles to use the bridge. The Queensboro Bridge is the first entry point into Manhattan in the course of the New York City Marathon and the last exit point out of Manhattan in the Five Boro Bike Tour.
The Queensboro Bridge is a two-level double cantilever bridge. It has two cantilever spans, one over the channel on each side of Roosevelt Island. The bridge does not have suspended spans, so the cantilever arm from each side reaches to the midpoint of the span. The lengths of its five spans and approaches are as follows:
Until it was surpassed by the Quebec Bridge in 1917, the span between Manhattan and Roosevelt Island was the longest cantilever span in North America.
