As of December 2012, 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).
