27 May 1937. The golden gate bridge opened to pedestrian traffic.

Some describe the Golden Gate Bridge as “possibly the most beautiful, certainly the most photographed, bridge in the world.” At the time of its opening in 1937, it was both the longest and the tallest suspension bridge in the world, with a main span of 4,200 feet (1,280 m) and a total height of 746 feet (227 m).
