| Golden Gate Bridge San Francisco, California
One of the longest suspension bridges in the world, the Golden Gate Bridge spans a channel at the entrance of San Francisco Bay and connects northern California to the peninsula of San Francisco. The bridge was designed by Joseph B. Strauss. It was opened to traffic on May 27, 1937, at a total cost of $35½ million. The official color of the bridge is International Safety Orange.
