World’s Longest Bridge over Water




This is the bridge that connects Qingdao, which is the most eastern port of China, with an airport in Huangdao city on the island of Hongdao. The bridge is T-shaped with 3 entry/exit points, transecting the Jiaozhou Bay. The bridge is part of Jiaozhou Bay Connection Project together with Qing-Huang tunnel as they’re opened both on June 30, 2011.


Jiaozhou Bay bridge has longitude of 42.5 km (26.4 miles) thus making it the world’s longest bridge over water and taking off the title from Lake Pontchartrain Causeway (Southern Louisiana, US) with 38.35km in length.

The Qingdao-Huangdao bridge was built in four years with the hard work of at least 10 000 workers and costs nearly $1.5 milliard to the Chinese government. Designer of the bridge is Shandong Gaosu Group and is supposed to withstand on earthquakes with level 8 by Richter and typhoons. The facility is held by nearly 5 000 pillars and has 35 meters width, which is enough for 6 lanes. Construction of the bridge takes 450 000 tons of steel and 2.3 million cubic meters of concrete.


As we mentioned above, Qing-Huang tunnel opened on the same day. The tunnel adds 9.47 km to the Jiaozhou Bay Connection Project, which makes 51.97 km length in total.
