The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the one-mile-wide (1.6 km) strait connecting San Francisco Bay and the Pacific Ocean. The structure links the U.S. city of San Francisco, California—the northern tip of the San Francisco Peninsula—to Marin County.
The Golden Gate Bridge’s clearance above high water averages 67 m while its towers, at 227 m above the water,were the world’s tallest on a suspension bridge until 1993 when it was surpassed by the Mezcala Bridge, in Mexico.The design and construction of Golden gate bridge lead to revolution in Civil engineering. Let’s understand all the magical engineering behind the golden gate bridge. Watch the video from Lesics:
The weight of the roadway is hung from 250 pairs of vertical suspender ropes, which are attached to two main cables. The main cables pass over the two main towers and are fixed in concrete at each end.
Each cable is made of 27,572 strands of wire. The total length of galvanized steel wire used to fabricate both main cables is estimated to be 80,000 miles (130,000 km). Each of the bridge’s two towers has approximately 600,000 rivets./
