Golden Gate Bridge opened

May 27, 1937: San Francisco’s Golden Gate Bridge, a stunning technological and artistic achievement, opens to the public after five years of construction.

On opening day—“Pedestrian Day”—some 200,000 bridge walkers marveled at the 4,200-foot-long suspension bridge, which spans the Golden Gate Strait at the entrance to San Francisco Bay and connects San Francisco and Marin County. The next day, on May 28, the Golden Gate Bridge opened to vehicular traffic.

The concept of bridging the nearly mile-wide Golden Gate Strait was proposed as early as 1872, but it was not until the early 1920s that public opinion in San Francisco began to favor such an undertaking. In 1921, Cincinnati-born bridge engineer Joseph Strauss submitted a preliminary proposal: a combination suspension-cantilever that could be built for $27 million.
