Brooklyn Bridge is a suspension bridge over the East River. It connects the boroughs of Brooklyn and Manhattan in New York City. The main span of the bridge extends 1,595 feet (486 meters). It was the largest suspension bridge in the world when it was completed in 1883. Its total cost was about $15 million.
Brooklyn Bridge hangs from steel cables that are nearly 16 inches (41 centimeters) thick. The cables are suspended from 275-foot (84-meter) towers and are anchored at their ends to massive blocks of masonry. The bridge has six lanes for traffic. In 1964, the National Park Service designated the bridge a national historic landmark.
