What makes the Golden Gate Bridge so special?

After a little more than 4 years of construction, the bridge was the longest suspension bridge in the world when it was completed in 1937 and is still one of the longest suspension bridges today. If you also include the access bridges in the total length of the structure, it is 2.737 kilometers. In addition, the marvel of engineering, which quickly became the city’s landmark in California after its construction and opening, was built in just four years.

And there are also quite a few other records to be found when you look at the bridge over the Golden Gate. The pillars or pylons are tallest, the cables are the longest and the thickest. In addition, the masterpiece broke the record for the largest underwater foundations between San Francisco and Marin County.

The main cables have a diameter of 92 centimeters and a length of 2,332 meters. It is these main cables that keep the lane for road traffic, the cycle paths for the cyclists and the footpaths in suspension. The road is about 60 meters above the water surface. The clear passage height for navigation at high tide is 67 meters.

The longest suspension bridge in the United States is the Verrazano-Narrows Bridge in New York City. The Verrazano-Narrows Bridge is 18 meters longer than the Golden Gate Bridge.

Each of the two carrying cables is over 90 cm thick. The bridge weighs a total of 887,000 tons. Approx. 600,000 rivets were used in the landmark, with the last rivet being made of gold.

And there was a new highlight on the bridge in 2020. Because the world-famous bridge with a span of 1,280 meters and its high towers was built with a new railing that you can hear eerily singing or howling in the wind. The sounds of the building can be heard particularly clearly in westerly winds. Maybe you are lucky and it blows while you are at the bridge.
