The now-completed Qingdao Haiwan Bridge over Jiaozhou Bay in China is 26.4 miles long. It’s three miles longer than the Lake Pontchartrain Causeway in Louisiana, the previous holder of the world record for the longest bridge over water:
No longer dependent on western expertise for such sophisticated projects, the six-lane road bridge is supported by more than 5,200 columns and was designed by the Shandong Gausu Group. When it opens to traffic later this year, the bridge is expected to carry over 30,000 cars a day and will cut the commute between the city of Qingdao and the sprawling suburb of Huangdao by between 20 and 30 minutes.
The bridge is built to withstand an 8.0 Richter scale earthquake and take punishment from the occasional typhoon.
