Linking Manhattan island to Brooklyn, the mighty Brooklyn Bridge opened in 1883 after fourteen years under construction. The bridge’s main span is 486.3 m (1,595.5 ft) and it was the first steel-wire suspension bridge to be built. At the time, it was the longest suspension bridge in the world. It was originally named the New York and Brooklyn Bridge and later the East River Bridge. However, it became informally known as Brooklyn Bridge, and this name was officially adopted in 1915.
