Queensboro Bridge
The Queensboro Bridge carries New York State Route 25 (NY 25), which terminates at the bridge's western end in Manhattan, and also once carried NY 24 and NY 25A. The western leg of the Queensboro 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.
