The Brooklyn Bridge, one of the oldest suspension bridges in the United States, stretches 5,989 feet (1825 m) over the East River, connecting the New York City boroughs of Manhattan and Brooklyn (on Long Island). Upon completion, it was the longest suspension bridge in the world, the first steel-wire suspension bridge, and the first bridge to connect to Long Island. Originally referred to as the New York and Brooklyn Bridge, it was dubbed the Brooklyn Bridge in an 1867 letter to the editor of the Brooklyn Daily Eagle,and formally so named by the city government in 1915. Since its opening, it has become an iconic part of the New York skyline. It was designated a National Historic Landmark in 1964.
