The build began in 1933 and took four years Photograph: AFP/Getty Images The 4,200 foot long suspension span of the Golden Gate Bridge was the longest in the world - until 1964 when the Verrazano Narrow's Bridge in New York opened. Today the world's longest suspension bridge is the Akashi Kaikyo Bridge in Japan at 6,532ft Photograph: Hulton Archive/Getty Images Workers on the bridge. Eleven men died during construction, 10 of them on 17 February 1937 when a section of scaffolding carrying 12 men fell through the safety net. During construction the net saved the lives of 19 men who became known as the Halfway-to-Hell Club Photograph: AFP/Getty Images Military biplanes fly between the towers of the Golden Gate Bridge as pedestrians walk across the span during opening ceremonies on 27 May 1937.
