The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the opening of the San Francisco Bay onto the Pacific Ocean. As part of both U.S. Route 101 and California State Route 1, it connects the city of San Francisco on the northern tip of the San Francisco Peninsula to Marin County. The Golden Gate Bridge was the longest suspension bridge span in the world when it was completed during the year 1937, and has become an internationally recognized symbol of San Francisco and California. Since its completion, the span length has been surpassed by eight other bridges. It still has the second longest suspension bridge main span in the United States, after the Verrazano-Narrows Bridge in New York City. In 2007, it was ranked fifth on the List of America's Favorite Architecture by the American Institute of Architects. Despite its red appearance, the color of the bridge is officially an orange vermilion called international orange. The color was selected by consulting architect Irving Morrow because it blends well with the natural surroundings yet enhances the bridge's visibility in fog. The Golden Gate Bridge is the most popular place to commit suicide in the United States and is one of the most popular in the world. The deck is approximately 245 feet (75 m) above the water. After a fall of approximately four seconds, jumpers hit the water at some 86 miles per hour (138 km/h), which is often fatal in and by itself. Some of those who survive the initial impact, drown or die of hypothermia in the cold water. The weight of the roadway is hung from two cables that pass through the two main towers and are fixed in concrete at each end. Each cable is made of 27,572 strands of wire. There are 80,000 miles (129,000 km) of wire in the main cables. The bridge has approximately 1,200,000 total rivets. [READ THE REST OF THIS ARTICLE]
