The Golden Gate Bridge

The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the opening into the San Francisco Bay from the Pacific Ocean. The entire bridge including the approach spans is 1.7 miles (2727 m) long, whilst the main span between the towers is 4200 feet (1280 m). The two towers rise 746 feet (230 m) above the water. From its completion in 1937, the center span was the longest among suspension bridges until 1964 when the Verrazano Narrows Bridge was erected.
