How Was the Golden Gate Bridge Built?

How was the golden gate bridge built? First, huge concrete piers were constructed in the bay at each end of the bridge. Then the towers were built, and the cables drawn between them. Finally, sections of roadway were lifted into position, and connected to the marin and san francisco approach roads.

How Was the Golden Gate Bridge Built?

The Golden Gate Bridge is an iconic landmark in San Francisco, California. It spans the Golden Gate, the one-mile-wide (1.6 km) strait connecting San Francisco Bay and the Pacific Ocean. Its distinctive orange color and remarkable engineering feats have made it a symbol of the city for decades and one of the most photographed bridges in the world.

The bridge was designed by chief engineer Joseph Strauss in 1933 and construction began in January 1933. The bridge was built using the cantilever-suspension method, which meant that the two suspension towers, each 690 feet (210 m) high, were constructed first, followed by the cables and road deck.

Hundreds of workers labored under arduous conditions to build the bridge. The first challenge was to build the two suspension towers from which the cables that hold up the roadway would hang. Constructing the towers was a difficult and dangerous endeavor, with workers having to suspend themselves hundreds of feet over the bay in order to attach the cables to the towers.

The bridge was built with steel girders, which were connected to the suspension cables with massive eyebars. The eyebars were made of forged steel, each weighing as much as 3,500 pounds (1,600 kg).
