San Francisco’s Golden Gate Bridge turns 75 today. It was opened May 27th, 1937 after 5ive years of construction. On opening day 200,000 bridge walkers marveled at the 4200 foot-long suspension bridge which spans the Golden Gate Strait at the entrance to San Francisco Bay and connects San Francisco and Marin County. On May 28th the bridge opened to vehicular traffic. At 4200 feet it was the longest bridge in the world until the completion of New York City’s Verrazano Narrows Bridge in 1964. The cost today for a car traveling over the bridge is $6. They only collect when you are driving south though.
