The beautiful Golden Gate Bridge is the large suspension bridge located in San Francisco, spanning the gateway between the opening of the San Francisco Bay and the Pacific Ocean. The length of the bridge from abutment to abutment is 1.7 miles, the width is 97 feet and the bridge weighs around about 887 thousand tons including anchorages and approaches. The bridge is painted Orange Vermillion, also known as International Orange, and needs constant touch ups to make sure the salt content in the air does not erode it. When the Golden Gate Bridge was completed in 1937, it was the longest suspension bridge in the world. It is now the 2nd longest suspension bridge in the United States and the world's 9th longest suspension bridge.
