The Golden Gate Bridge from Baker Beach during its construction and today. The bridge that connects San Francisco to Marin County is considered the symbol of the Bay Area and California.
The construction started in 1933 and lasted 4 years during which it encountered many technical challenges. 1.2 million steel rivets and more than 80,000 miles of wire were installed - enough to wrap around the world more than three times. Eleven people died from fall. At the time of its opening in 1937 it was the longest and highest suspension bridge in the world, in 1995 it was declared a modern wonder of the world.
At the time the old photo was taken, the towers and horizontal cables were already being built; the vertical wire ropes and the road are still missing.
