Hangzhou Bay Bridge (simplified Chinese: 杭州湾大桥; traditional Chinese: 杭州灣大橋; pinyin: Hángzhōu Wān Dàqiáo) is a highway bridge with a cable-stayed portion across Hangzhou Bay in the eastern coastal region of China. It connects the municipalities of Jiaxing and Ningbo in Zhejiang province.
Construction of the bridge was completed on June 14, 2007. The bridge was opened to public May 1, 2008 at a cost of 11.8 billion yuan, after a considerable period of testing and evaluation. The bridge shortened the highway travel distance between Ningbo and Shanghai from 400 km to 180 km and reduced travel time from 4 to 2 hours. At 35.673 km in length, Hangzhou Bay Bridge was among the ten longest trans-oceanic bridges.
The Hangzhou Bay Bridge is of the cable stayed bridge form. This form was chosen for this project because of the strength of the cable stayed bridge in adverse conditions. The bridge was constructed in the Qiantang River and Yangtze River Deltas and Hangzhou Bay, which all experience some of the highest tidal bore forces on the planet. The location of the bridge is also prone to earthquakes, as well as extremely high winds during typhoon season.

Service centre of Hangzhou Bay Bridge
A 10,000-square-metre (110,000 sq ft) service centre called Land between the Sea and the Sky (Chinese: 海天一洲, Pinyin: Hǎitiān Yīzhōu) is built in the middle of the bridge. This centre contains a resting area, a restaurant, a gas station, a hotel, a conference room, and a lookout tower, which serves as a tourist attraction to watch the tide. The service centre is built on an island, which is a platform resting on piers to avoid obstructing the sea current in the bay.
a second bridge across Hangzhou Bay
A plan to build a second bridge across Hangzhou Bay, which will reduce the drive time between Shanghai and Ningbo to less than two hours, was granted approval yesterday.
The 66-kilometer span, of which 54km will be over water, will link Shanghai’s Jinshan District with Cixi City in Ningbo, Zhejiang Province, the Ningbo government said.
The road-rail bridge will reduce the distance between Shanghai and Ningbo to 160km from 200km, officials said.
The government did not provide cost for the project, but said its traffic infrastructure budget for the year, which includes the new bridge, is 18.1 billion yuan (US$2.95 billion).
The new bridge is part of a wider scheme to improve traffic links between Yangtze Delta cities.
