Jiaozhou Bay Bridge, is a roadway bridge in eastern China’s Shadong 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 miles) long, making it
according to Guinness World Records the world’s longest bridge over water
as of July 2011. China is already home to seven of the world’s 10 longest bridges, including the world’s lengthiest, the 102 mile Danyang-Kunshan rail bridge, which runs over land and water near Shanghai. And with Beijing pumping billions into boosting China’s infrastructure, the Qingdao Haiwan Bridge will not be the world’s longest sea bridge for very long as coming 2016, it is due to be surpassed by an even longer structure, linking Hong Kong with the Guangdong province. The longest bridge over water “continuous length” is the Lake Pontchartrain Causeway, the difference being the latter 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 meters of concrete were used in the
construction of the bridge, which was designed by the Shandong Gaosu Group. It is designed to beable to withstand severe earthquakes, typhoons, and collisions with ships. The bridge is supported by more than 5,000 pillars, 35 meters (115 feet) wide, carrying six lanes and two shoulders, and cost more than 10 billion Yuan (US$1.5 billion).
On the same day the bridge opened, the Qing-Huang Tunnel opened. It also transects Jiaozhou Bay, also connecting Huangdao District and the city of Qingdao, between the narrow mouth of the bay which is 6.17 kilometers (3.83 mi) wide.The tunnel is 9.47 kilometers (5.88 mi) long.
Concerns regarding the bridge’s safety were raised when Chinese media
reported that the bridge was opened with faulty elements, such as “incomplete crash-barriers, missing lighting and loose nuts on guard-rails”, with workers stating that “it would take two months before finishing all of the projects related to the bridge”. Shao Xinpeng, the bridge’s chief engineer, claimed that in spite of the safety report the bridge was safe and ready for traffic, adding that the problems highlighted in the reports were not major.
