Jiaozhou Bay Bridge – The World’s Longest Sea Bridge

China is the home to most of the longest bridges in the world. The Jiaozhou Bay Bridge is another addition to the long list of records. It is a roadway bridge that links China’s eastern port city of Qingdao to an airport built on a nearby island and the industrial suburb of Huangdao. The aggregate length of the bridge is 41.58 kilometers. It is recorded as the world’s longest bridge over water in the Guinness Book of World Records. The Jiaozhou Bay Bridge is also the longest sea bridge in the world. China already hosts the world’s longest bridge ever, the Danyang-Kunshan rail bridge.

The huge Y-shaped bridge stretches across the wide blue waters of Jiaozhou bay. The bridge was entirely designed by Chinese engineers at the Shandong Gausu Group. It is supported by more than 5,000 pillars across the bay and took four years to build. More than 10,000 workers toiled in two teams around the clock to build the bridge. The Jiaozhou Bay Bridge is almost three miles longer than the previous record-holder – the Lake Pontchartrain Causeway in Louisiana. The Jiaozhou Bay Bridge made use of many innovations in structural engineering. The cable-stayed bridge lent uniqueness and simplicity to the structure.

The Jiaozhou Bay Bridge has three navigable sections: the Cangkou Channel Bridge, the Dagu Channel Bridge and the Hongdao Channel Bridge. It opened on 30 June 2011 for traffic.
