The Hangzhou Wan Daqiao ( Chinese 杭州 灣 大橋 / 杭州 湾 大桥 , Pinyin Hángzhōu Wān Dàqiáo , English Hangzhou Bay Bridge ) is a bridge that spans Hangzhou Bay on the east coast of China. The bridge connects Cixi , which is 25 km northwest of Ningbo , with Jiaxing and thus shortens the distance between Shanghai and Ningbo by 120 km. With a length of 36 km, it was the longest sea bridge in the world when it opened in 2008. In 2011 it lost that status to the Jiaozhou Bay Bridge . The structure consists of two cable-stayed bridges with 448 m and 318 m span. The Hangzhou Bay Ring Highway (G92) runs over the bridge .
Building history
Construction of the bridge began on June 8, 2003. Both parts of the bridge were connected to each other on June 26, 2007 and on May 1, 2008, earlier than planned, the bridge was opened to traffic. 11.8 billion yuan (equivalent to around 1.4 billion euros ) was invested in the construction, about half of which came from private companies from Ningbo. A total of ten years passed for planning and construction. The chief architect was Lin Guoxiang. More than 600 experts from various disciplines were involved in the preparation of the project. The foundation of the pillars was particularly problematic because the tidal range of over nine meters in the shallow bay and the porous seabed presented a major challenge.
structure
The Hangzhou Bay Bridge consists of nine sections. The two cable-stayed bridges are particularly complex. Pylons almost 100 meters high hold the tension ropes. 660 bridge arches and 7000 pillars, which are around 70 meters high, support the structure. The larger of the two passages has a pylon span of 448 m, the passage width is 408 m. The bridge is designed to withstand wind speeds of up to 230 km / h. The steel companies involved gave a guarantee for the beam parts for the next 100 years. A total of 800,000 tons of steel and 2.5 million tons of concrete were used. About halfway, in the middle of the sea, a service island has now been built that includes a rest stop, restaurants, a hotel, a conference center and a viewing platform.
