Jiaozhou Bay Bridge (or Qingdao Haiwan Bridge) is a 26.7 km (16.6 mi) long roadway bridge in eastern China's Shandong province, which is part of the 41.58 km (25.84 mi) Jiaozhou Bay Connection Project. As of December 2012[update], Guinness World Records lists the Jiaozhou Bay Bridge as the world's longest bridge over water (aggregate length) at 41.58 km (25.84 mi).
The Jiaozhou Bay Bridge transects Jiaozhou Bay, which reduces the road distance between Qingdao and Huangdao by 30 km (19 mi), compared with the expressway along the coast of the bay, reducing travel time by 20 to 30 minutes. The design of the bridge is T-shaped with the main entry and exit points in Huangdao and the Licang District of Qingdao. A branch to Hongdao Island is connected by a semi-directional T interchange to the main span. The construction used 450,000 tons of steel and 2.3 million cubic metres (81×106 cu ft) of concrete. The bridge is designed to be able to withstand severe earthquakes, typhoons, and collisions from ships. It is supported by 5,238 concrete piles. The cross section consists of two beams in total 35 m (115 ft) wide carrying six lanes with two shoulders.
The Jiaozhou Bay Bridge has three navigable sections: the Cangkou Channel Bridge to the west, the Dagu Channel Bridge to the east, and the Hongdao Channel Bridge to the north. The 600 metres (2,000 ft) long Cangkou Channel Bridge has 260 m (850 ft) the largest span of the entire Jiaozhou Bay Bridge. The Hongdao Channel Bridge has a span of 120 m (390 ft). The non-navigable sections of the bridge have a span of 60 m (200 ft).
The length of the Jiaozhou Bay Bridge is 26.7 km (16.6 mi), of which 25.9 km (16.1 mi) are over water, representing the aggregate length of three legs of the bridge.
The Jiaozhou Bay Bridge is part of the Jiaozhou Bay Connection Project, which includes overland expressways and the Qingdao Jiaozhou Bay tunnel. The aggregated length of the project is 41.58 km (25.84 mi), which is by many sources listed as length of the Jiaozhou Bay Bridge.
