 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.
The Madison Street Bridge, or Madison Bridge, refers to two different bridges that spanned the Willamette River in Portland, Oregon, from 1891 to 1900 and from 1900 to 1909.

 The original and later bridges are sometimes referred to as Madison Street Bridge No. 1 and Madison Street Bridge No. 2, respectively.
 The second bridge, built in 1900, has alternatively been referred to as the "rebuilt" Madison Street Bridge (of 1891), rather than as a new bridge, because it was rebuilt on the same piers. Both were swing bridges, whereas their successor, the Hawthorne Bridge, is a vertical-lift-type.
