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.
