Here are some of the coolest facts that you should know about San Francisco’s Golden Gate Bridge:
Longest Suspension Bridge
Spanning 4,200 feet long, the Golden Gate Bridge was the world’s longest suspension bridge until the title was taken by the Verrazano Narrows Bridge in New York City (1964).
Weighs a Ton
Upon its completion in May 1937, the bridge weighed a total of 894,500 tons.
Rivets upon Rivets
In its construction, over 1,200,000 rivets were used in the bridge’s two towers.
Orange in Colour
The steel that was used in the construction was coated in an orange-tinted primer to protect it, during delivery, from the elements. The orange was preferred by the bridge’s architect, stating that the orange would be more visible in the Bay’s foggy conditions. Today, the bridge is painted using Sherwin-William’s custom formula of orange, called “International Orange”
Chief Engineer, Joseph Strauss, took safety seriously. The Golden Gate Bridge project was one of the first in which a safety net was installed under the deck bridging to protect workers in the event they fell off the bridge. During the construction project, the net saved a total of 19 workers.
Hard Hats Mandatory
The Golden Gate Bridge was the world’s first construction site where workers were required to wear a hard hat.
Less Fatalities than Anticipated
During the time of the bridge’s construction, a certain number of fatalities were anticipated for large-scale bridge projects. Generally, 1 fatality per $1 million spent occurred. Given that the bridge cost $35 million to construct, the total fatality rate of 11 was considered a win.
