How was the Golden Gate Bridge constructed?
One of the factors which made its construction “IMPOSSIBLE” were the mud and silt in the Bay and the depth of the sea water. Building work started at each end where huge concrete blocks were sunk deep into the earth and to which the 200-odd steel cables from which the bridge would be suspended were to be anchored.
Why was the Golden Gate Bridge difficult to build?
It was known as “the bridge that couldn’t be built ”. This was due to the complex challenges presented by the strait; strong tides, wind, fog, and the San Andreas Fault located just 7 miles offshore. But improvements in long-span bridge design led to the hope that it could eventually be accomplished.

How is a bridge built underwater?
When bridges requiring piers are built over a body of water, foundations are made by sinking caissons into the riverbed and filling them with concrete. In the case of suspension bridges , towers are built atop the caissons. The first suspension- bridge towers were stone, but now they are either steel or concrete.
Are there sharks under the Golden Gate Bridge?

What two cities does the Golden Gate Bridge connect?
The Golden Gate Bridge is an iconic structure connecting the city of San Francisco to Marin County , California. It spans almost two miles across the Golden Gate, the narrow strait where San Francisco Bay opens to meet the Pacific Ocean .
Why is the Golden Gate Bridge a frame structure?
The frame structure allows the bridge to be the correct size. It is not to heavy nor to light. Since it is a suspension bridge it was made to cover a long distance from across the bay. If it was a mass structure it would be to heavy and would collapse.
