The Golden Gate Bridge was envisioned in 1917 by engineer Joseph Baermann Strauss. Strauss confronted 12 years of opposition to the idea of bridging the Golden Gate. Military leaders and shippers were concerned that the bridge would bottle up the harbor and ferryboat operators feared for their livelihood. He finally sold the public on the idea and in 1930 six coastal counties approved bonds to build the Golden Gate Bridge. Construction began in 1933 with the North Pier. Even then, the pier was the subject of intense debate over the question of whether the structure could withstand an earthquake. The foundation for the North Pier extends 100 feet below the surface and 35 feet into the bedrock.
