On 5 January, 1933, construction starts on the Golden Gate Bridge, as employees started excavating 3.25 million cubic feet of dirt for the structure’s huge anchorages.
Following the Gold Rush boom that began in 1849, speculators realized the land north of San Francisco Bay would increase in value in direct proportion to its accessibility to the city. Soon, a plan was hatched to build a bridge that would span the Golden Gate, a narrow, 400-foot deep strait that serves as the mouth of the San Francisco Bay, connecting the San Francisco Peninsula with the southern eliminate of Marin County.
Although the essential idea returned so far as 1869, the proposal took root in 1916. A previous engineering college student, James Wilkins, working as a journalist with the SAN FRANCISCO BAY AREA Bulletin, needed a suspension bridge with a middle period of 3,000 ft, double the space of any around almost. Wilkins’ idea was approximated to cost a fantastic $100 million. So, San Francisco’s city engineer, Michael M. O’Shaughnessy (he’s also credited with discovering the name Golden Gate Bridge), started asking bridge engineers whether maybe it’s done by them for less.
Poet and engineer Joseph Strauss, a 5-feet high Cincinnati-born Chicagoan, said he could.
Eventually, O’Shaughnessy and Strauss concluded they could create a pure suspension bridge within a practical selection of $25-30 million with a primary span at least 4,000 feet. The building plan experienced opposition, including litigation, from many resources. By the right time the majority of the obstacles were cleared, the fantastic Depression of 1929 got begun, limiting funding options, so officials persuaded voters to aid $35 million in bonded indebtedness, citing the working careers that might be designed for the task. However, the bonds couldn’t be sold until 1932, when San-Francisco centered Loan company of America decided to buy the whole task to be able to help the neighborhood economy.
The Golden Gate Bridge officially opened on May 27, 1937, the longest bridge span in the world at the time. The first public crossing had taken place the day before, when 200,000 people walked, ran and even roller skated over the new bridge.
With its tall towers and famous red paint job, the bridge quickly became a famous American landmark, and a symbol of San Francisco.
