The most photographed bridge in the world was completed in May 1937 after 52 months of construction and a cost of $35 million. Designed by Joseph Strauss, it was the longest suspension bridge in the world at that time, at a length of 1.2 miles. It was designed to withstand winds of up to 100mph as it swings up to 27 ft. The bridge connects San Francisco and the Presidio to the Marin Headlands in Marin County to the north. Its name comes from the 'gateway to the gold' harbor entrance named during the Gold Rush. The official paint color is 'international orange' It takes a team of 25 people 11 1/2 months to paint and it is painted every year, using 1000 gallons of paint a week.
