Golden Gate Bridge Construction Begins

Context

Proposals for a bridge across the Golden Gate Strait dated back to the 1860s, when land speculators noted that easier access would boost property values north of San Francisco Bay. Ferries had long connected the city to Marin County, but growing population and commerce after the Gold Rush made a fixed crossing increasingly attractive. In 1916, journalist and former engineer James Wilkins publicly advocated a suspension bridge with a 3,000-foot main span, prompting San Francisco city engineer Michael M. O’Shaughnessy to solicit designs from professionals across the country.

What Happened

Joseph Strauss, a Chicago-based engineer who had built hundreds of smaller spans, submitted a feasible plan and was later named chief engineer by the newly formed Golden Gate Bridge and Highway District. After years of engineering studies, War Department permits, and voter approval of a $35 million bond issue in 1930, financing was secured when the Bank of America purchased the bonds in 1932. On January 5, 1933, crews started the official work by removing millions of cubic feet of earth to create the massive concrete anchorages on both the San Francisco and Marin shores.

Aftermath

Construction proceeded through the depths of the Great Depression, providing steady employment to thousands of workers. The project advanced in stages, with piers, towers, and eventually the suspension cables taking shape over the next four years despite occasional setbacks from weather and equipment losses.

Legacy

When the bridge opened in May 1937 it held the record for the longest suspension span and established new standards for both engineering scale and aesthetic design. It transformed regional transportation, spurred development in the North Bay, and became a enduring emblem of American infrastructure achievement during the twentieth century.
