The Golden Gate Bridge was built simply, to connect San Francisco to Marin County. The San Francisco Bay has rough currents and ferries were the only way to get across. Building a bridge just made it easier.
One of the most interesting Golden Gate Bridge facts is that only eleven workers died during construction, a new safety record for the time. In the 1930s, bridge builders expected 1 fatality per $1 million in construction costs, and builders expected 35 people to die while building the Golden Gate Bridge.One of the bridge's safety innovations was a net suspended under the floor.he Golden Gate Bridge was the longest span in the world from its completion in 1937 until the Verrazano Narrows Bridge was built in New York in 1964. Today, it still has the ninth-longest suspension span in the world.
