Eighty years ago today, on April 19th1937, the Golden Gate Bridge was completed connecting the city of San Francisco with Marin County. It spans approximately 1.7 miles across the San Francisco Bay as one of the great engineering wonders of the modern world.
Three chief engineers are credited with its design – Joseph Strauss, Irving Morrow and Charles Ellis – as a suspension bridge with truss arches and truss causeways. The actual construction of the bridge took four years to complete and was plagued by numerous problems. Yet after years of fast-rising tides, frequent storms, San Francisco’s famous fog and difficulty of blasting through bedrock 30 metres below the bay surface to anchor earthquake-proof foundations, the bridge was completed in April of 1937.
Today still, its distinct orange vermillion steel skeleton is recognized all over the world as arguably San Francisco’s greatest attraction. Users of the bridge are promised a spectacular view from the six-lane roadway, which also includes a pedestrian walkway and bicycle lane built on either side of the bridge.
