Golden Gate Bridge, which connects the city of San Francisco on the northern tip of the San Francisco Peninsula to Marin County, is the most internationally recognized symbols of San Francisco, California, and of the United States.
It was the longest among suspension bridges until 1964 when the Verrazano-Narrows Bridge was erected.
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.
