On this day 78 years ago, construction began on the Golden Gate Bridge connecting the San Francisco peninsula with Marin County. When the bridge officially opened in 1937, it was the longest suspension bridge in the world and cost $35 million. The roadway is suspended from two cables that pass through the two main towers and are secured in anchorages at each end. Each cable is made of 27,572 strands of wire, and it took more than six months to spin them.
Another record set by the bridge, though unintended: It is the most popular bridge in the world to commit suicide from, and the fatality rate of jumping from the bridge is roughly 98 percent. These sober facts inspired the 2006 documentary film “The Bridge.”
