Queensboro Bridge

This structure—officially renamed the Ed Koch Queensboro Bridge in 2010—was completed in 1909. Since then, it's played a vital role in the development of the metropolis. Its 7,449-foot length originally accommodated rail tracks on its upper deck and a tram line on the lower level. Today the spans support more than 176,000 cars daily. The double-decked cantilever design has inspired countless New Yorkers—including the Queens-bred Paul Simon, who eulogized the structure in 1966 in “The 59th Street Bridge Song (Feelin’ Groovy),” and Woody Allen, who memorably gazed upon the bridge with Diane Keaton in his 1979 film Manhattan.
