golden gate bridge facts when was it built
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). Today, the Golden Gate Bridge is neither the longest nor the tallest in the world, but remains the tallest bridge in the United States.
Golden Gate Bridge Strauss was chief engineer in charge of overall design and construction of the bridge project.[14] However, because he had little understanding or experience with cable-suspension designs,[22] responsibility for much of the engineering and architecture fell on other experts. Strauss's initial design proposal (two double cantilever spans linked by a central suspension segment) was unacceptable from a visual standpoint. The final graceful suspension design was conceived and championed by Leon Moisseiff, the engineer of the Manhattan Bridge in New York City.[23]
San Francisco–Oakland Bay Bridge Tolls were subsequently raised to finance improvements to the bridge approaches, required to connect with new freeways, and to subsidize public transit in order to reduce the traffic over the bridge.
West Gate Bridge Construction resumed in 1972, with the bridge being completed in 1978. After 10 years of construction, the bridge, a part of the larger West Gate Freeway, cost $202 million.[1]
