The Queensboro, officially the Ed Koch Queensboro Bridge, but known by locals by one of two other names depending on the side, is a cantilever bridge over the East River in New York City. Completed in 1909, it connects the Long Island City neighborhood in the borough of Queens with the East Midtown and Upper East Side neighborhoods in Manhattan, passing over Roosevelt Island. Because the western end of the bridge connects to 59th Street in Manhattan, it is also called the 59th Street Bridge by Manhattanites. The bridge consists of five steel spans measuring 3,725 ft (1,135 m) long; including approaches, its total length is 7,449 ft (2,270 m). The Queensboro Bridge carries New York State Route 25 (NY 25), which terminates at the bridge's western end in Manhattan. The bridge has two levels: an upper level with a pair of two-lane roadways, and a lower level with four vehicular lanes flanked by a walkway and a bike lane. The western leg of the Queensboro Bridge is paralleled on its northern side by the Roosevelt Island Tramway. The bridge is one of four vehicular bridges directly connecting Manhattan Island and Long Island, along with the Williamsburg, Manhattan, and Brooklyn bridges to the south. It lies along the courses of the New York City Marathon and the Five Boro Bike Tour. Serious proposals for a bridge linking Manhattan to Long Island City were first made as early as 1838, but various 19th-century plans to erect such a bridge, including two proposals by Queens doctor Thomas Rainey, never came to fruition. After the creation of the City of Greater New York in 1898, plans for a city-operated bridge were finalized in 1901. The bridge opened for public use on March 30, 1909, and was initially used by pedestrians, horse-drawn and motor vehicles, elevated trains, and trolleys. Elevated service ceased in 1942, followed by trolley service in 1957. The upper-level roadways were built in the early 1930s and the late 1950s. Designated as a New York City landmark in 1973, the bridge was renovated extensively from the late 1970s to the 1990s. The bridge was officially renamed in 2011 in honor of former New York City mayor Ed Koch, and another renovation occurred in the early 2020s.
Name The Queensboro Bridge was originally named for the borough of Queens and was the third bridge across the East River to be named after a New York City borough, after the Brooklyn Bridge and the Manhattan Bridge. By the late 20th century, the Queensboro Bridge was also known as the 59th Street Bridge because its Manhattan end is located between 59th and 60th streets. This name caused controversy among Queens residents who felt that the 59th Street Bridge name did not honor the borough of Queens. In December 2010, mayor Michael Bloomberg announced that the bridge would be renamed in honor of former mayor Ed Koch; the bridge had been renovated extensively in the 1980s, when he was mayor. The Ed Koch Queensboro Bridge name was formalized on March 23, 2011. The renaming was unpopular among Queens residents and business leaders; The Los Angeles Times wrote that Queens residents found the renaming disrespectful to their borough. The general public continued to call it the Queensboro Bridge years after the renaming. New York City Council member Peter Vallone Jr. of Queens proposed removing Koch's name from the bridge in 2013. and Mayor Mamdani has also suggested removing Koch's name from the bridge title.
Description The Queensboro Bridge is a two-level double cantilever bridge, with separate cantilevered spans over channels on each side of Roosevelt Island joined by a fixed central truss. In all, it has five steel truss spans, as well as approach viaducts on either side. The total length of the five spans, between the anchorages on the Manhattan and Queens sides, are approximately 3,725 ft (1,135 m), of which 2,166 feet (660 m) are above water. In addition, there is a 1,052-foot-long (321 m) approach viaduct in Manhattan and a 2,588-foot-long (789 m) approach viaduct in Queens, connecting the anchorages on either side to street level. This brings the bridge's total length to 7,449 feet (2,270 m). The bridge carries New York State Route 25, which ends at the span's western terminus.
