Thousands celebrate 75th anniversary of Golden Gate Bridge

Tens of thousand of people came to San Francisco’s waterfront on Sunday to mark the 75th anniversary of the Golden Gate Bridge, the distinctive orange vermilion structure that attracts some 10mn visitors each year. The city hosted a massive celebration complete with music, dance vintage cars and motorcycles, as well as a fireworks display showcasing the iconic bridge at the entrance to the San Francisco Bay. The celebrations took place 75 years to the day after the bridge was opened to the public: to pedestrians on May 27, 1937, and to traffic the next day. At the time, the Golden Gate was the world’s longest suspension bridge. Dreamt up by engineer Joseph Strauss, the bridge distinguishes itself by its unique colour, chosen by architect Irving Morrow and dubbed International Orange. The paint originally ensured visibility for passing ships and served as a sealant to protect the bridge from the salty mist from the Golden Gate Strait after which it was named, the entrance to the bay from the Pacific Ocean. Construction of the bridge took four years. Some 1.7 miles (2.7km) long, it is 90ft (27m) wide and its two towers reach 746ft above sea level. Traffic is suspended 220ft above the water. Pedestrians and cyclists can access the bridge along with motorists.
