The Golden Gate Bridge in San Francisco is celebrating its diamond jubilee this year. For the past 75 years, the 1.7-mile suspension bridge has not only connected the northern tip of San Francisco to lush Marin County headlands, it has also become one of the most recognized American icons. The yearlong celebration is aptly titled “Bridging Us All.”
After opening in 1937, the Golden Gate Bridge kept the title of the world’s longest suspension bridge for a good part of three decades. Over time it has weathered the test of, well, weather: Constant fog, treacherous gusts and seismic movements have kept engineers busy maintaining the vermilion steel structure.
