The dream of spanning the Golden Gate Strait had been around for well over a century before the Golden Gate Bridge opened to traffic on May 28, 1937. Pedestrian Day was held on May 27, 1937.

The Golden Gate Bridge is a suspension bridge spanning the Golden Gate strait, the 1 mile (1.6 km) wide, 3 mile (5 km) long channel between San Francisco Bay and the Pacific Ocean.ntil 1964, the Golden Gate Bridge had the longest suspension bridge main span in the world, at 4,200 feet (1,300 m). Since 1964 its main span length has been surpassed by ten bridges; it now has the second-longest main span in the United States, after the Verrazano-Narrows Bridge in New York City.
