Jiaozhou Bay Bridge is a roadway bridge in eastern China’s Shandong province. It transects Jiaozhou Bay, connecting Huangdao District, the city of Qingdao and Hongdao Island (the bridge is “T” shaped with 3 entry/exit points). Opened on 30 June 2011, it reduces the road distance between Qingdao and Huangdao. The bridge opened at the same time as the nearby Qing-Huang Tunnel, both part of the Jiaozhou Bay Connection Project.
Jiaozhou Bay Bridge is 42.5 kilometres (26.4 mi) long, making it according to Guinness World Records the world’s longest bridge over water (aggregate length) as of July 2011. The longest bridge over water “continuous length” is the Lake Pontchartrain Causeway, the difference being the later runs continuously over water while Jiaozhou Bay Bridge has parts over land. It is estimated Jiaozhou Bay Bridge is over water for 25.5 kilometres (15.8 mi).
The bridge took four years to build, and employed at least 10,000 people. 450,000 tons of steel and 2.3 million cubic metres of concrete were used in the construction of the bridge, which was designed by the Shandong Gaosu Group. It is designed to be able to withstand severe earthquakes, typhoons, and collisions with ships. The bridge is supported by more than 5,000 pillars, 35 metres (115 ft) wide, carrying six lanes and two shoulders, and cost more than 10 billion yuan (US$1.5 billion).
