Golden Gate Bridge, standing today as a symbol of human intelligence and determination, is undoubtedly one of the greatest architectural wonders built across the World till date. The bridge connects San Francisco with Marin County covering gigantic natural basin spread across 500 square miles with around 16 rivers emptying their water into it. Bridge stands against force of winds flowing with the speed of 60 miles an hour.
The Concept Came into Picture
History of Golden Gate Bridge stretches back in 1921 when Chicago trained engineer Joseph Strauss confidently put his idea to build bridge over Golden Gate for mere $27 million. The construction of bridge was opposed by diverse layers of society, including military, railroads and lodgers, for their own self-centered grounds and it resulted into rejection of his design. After a couple of years, Charles Ellis, professor at University of Illinois, redesigned the bridge as a part of Strauss’s team.
Construction became live!
The main hurdle in the construction was “flowing” Pacific Ocean in basin and winds of over 60 miles velocity. To build strong concrete base, they first built fenders in violent flow of water and then took out 35.6 million liters of water to fill the cavity with concrete.
The other major difficulty was finance. It took 10 years for design to come into reality when $35 million were raised from bonds. Construction began live in 1933 and then it took only 4 years for it to complete. The bridge was open to public in 1937 and since then it has been assisting over 41 millions crossing each year.
