what's the length of the golden gate bridge
Golden Gate Bridge The Frommer's travel guide describes the Golden Gate Bridge as "possibly the most beautiful, certainly the most photographed, bridge in the world."[8][9] At the time of its opening in 1937, it was both the longest and the tallest suspension bridge in the world, with a main span of 4,200 feet (1,280 m) and a total height of 746 feet (227 m).
Golden Gate Bridge Construction began on January 5, 1933.[10] The project cost more than $35 million,[30] ($493 million in 2016 dollars[31]) completing ahead of schedule and $1.3 million under budget.[32] The Golden Gate Bridge construction project was carried out by the McClintic-Marshall Construction Co., a subsidiary of Bethlehem Steel Corporation founded by Howard H. McClintic and Charles D. Marshall, both of Lehigh University.
