The Brooklyn Bridge is one of the oldest suspension bridges in the United States. Completed in 1883, it connects the New York City boroughs of Manhattan and Brooklyn by spanning the East River. With a main span of 1,595.5 feet and 272 feet height, it was the longest suspension bridge in the world from its opening until 1903, and the first steel-wire suspension bridge. It is highly recognizable landmark and cultural icon. The dramatic buttressed gothic towers are constructed entirely of granite. Each of the four cables is capable of sustaining a live load of 12,000 tons. The roadway platform is hung on two-inch diameter steel suspenders strung from two pairs of cables - the catenaries - sixteen inches in diameter. Each cable is composed of 5,296 galvanized steel wires (the total length of wire used is 14,357 miles. Since its opening, it has become an iconic part of the New York skyline. It was designated a National Historic Landmark in 1964 and a National Historic Civil Engineering Landmark in 1972
