"Named one of the "Seven Wonders of the Modern World" by the American Society of Civil Engineers, the Golden Gate Bridge opened in 1937, connecting San Francisco with the surrounding northern counties. With a length of 8,981 feet and main span length of 4,200 feet, it is one of the longest single-span suspension bridges ever built. Its two massive towers are the highest bridge towers in the U.S., at 746 feet above the water. A clearance of 220 feet allows passage of the largest oceangoing vessels. Additional construction statistics are presented on a cross-section of one of the bridge's main cables, displayed near the Joseph B. Strauss Statue." (Source: A sightseer's guide to engineering)
"As with many civil engineering projects in their conceptual stages, naysayers scoffed at the Golden Gate Bridge. They said it would be technically unfeasible or too expensive to bridge the Golden Gate, a 1.7-mile-wide opening separating the Pacific Ocean from the San Francisco Bay. They said that the channel was too deep; the tides and winds too strong; the span too long.
Bridge designer Joseph Baermann Strauss believed such a bridge was not only feasible, but could be built for just $25 to $30 million. Out of 11 proposals from bridge engineering firms across the country, Strauss' was selected and he became Chief Engineer. Final engineering plans were submitted on August 27, 1930, and construction began in November 1932.
In what would become one of the safest construction job sites in its time, Strauss and his team of engineers and consultants, along with a dedicated staff of thousands of builders and workers, built one of the boldest, most spectacular bridges ever." (Source: ASCE)
