when did they build 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 Strauss remained head of the project, overseeing day-to-day construction and making some groundbreaking contributions. A graduate of the University of Cincinnati, he placed a brick from his alma mater's demolished McMicken Hall in the south anchorage before the concrete was poured. He innovated the use of movable safety netting beneath the construction site, which saved the lives of many otherwise-unprotected ironworkers. Of eleven men killed from falls during construction, ten were killed on February 17, 1937, when the bridge was near completion when the net failed under the stress of a scaffold that had fallen.[33] According to Travel Channel's Monumental Mysteries, the workers' platform that was attached to a rolling hanger on a track collapsed when the bolts that were connected to the track were too small and the amount of weight was too great to bear. The platform fell into the safety net, but was too heavy and the net gave way. Two out of the twelve workers survived the 200-foot (61Â m) fall into the icy waters, including the 37-year-old foreman, Slim Lambert. Nineteen others who were saved by the net over the course of construction became members of their Half Way to Hell Club.[34]
National World War II Memorial Ground was broken in September 2001. The construction was managed by the General Services Administration.
New Covent Garden Market Construction began in 1971 on the site of the former Nine Elms Locomotive Works, and the market opened on 11 November 1974.
