The Golden Gate Bridge is one of the world's famous bridges and a miracle of modern bridge engineering. The bridge stands over the 1,900-meter-long Golden Gate Strait in San Francisco, California, USA. It took 4 years to build, using more than 100,000 tons of steel and costing US$35.5 million. It was built by bridge engineer Joseph Strauss (1870-1938). year) design. Due to its historical value, the United Kingdom and the United States co-produced a documentary of the same name on the Golden Gate Bridge in 2007.
History
In 1579, British explorer Francis Drake discovered a strait connecting the Pacific Ocean and San Francisco, which later became the Golden Gate. Although the name had been used before the Gold Rush of 1849, the Gold Rush made the Golden Gate an integral part of California's mysterious charm. As early as 1872, people had discussed the idea of building a bridge across the Golden Gate Strait, but it was not until January 1933 that construction of the Golden Gate Bridge began, and it was first completed and opened to traffic in May 1937. The Golden Gate Bridge, which took more than 4 years to build, spans the north and south, connects the city of San Francisco to Marin County, and has become one of the most beautiful structures in the world. Although it is no longer the longest suspension bridge in the world, it is the most famous. The huge tower of the Golden Gate Bridge is 227 meters high. Each steel cable weighs 6,412 metric tons and is made of 27,000 steel wires.
Features
The color of the Golden Gate Bridge is international orange. Architect Alvin Morrow believed that this color would not only harmonize with the surrounding environment, but also make the bridge more eye-catching in the heavy fog that is common in the Golden Gate Strait. Due to its novel structure and otherworldly appearance, the bridge is widely regarded as a model of beauty by the international bridge engineering community, and has been named one of the wonders of the modern world by the American Society of Architectural Engineers. It is also one of the most photogenic bridges in the world. As part of the maintenance work of the Golden Gate Bridge, continuous painting of the bridge body is one of the components.
