It connects the municipalities of Jiaxing and Ningbo in Zhejiang province. At 35.673 km (22 mi) in length, Hangzhou Bay Bridge is the longest trans-oceanic bridge in the world, but it does not have the longest cable-stayed main span. It is also second in the world in overall length, with the Lake Pontchartrain Causeway in the United States being 2.8 kilometers longer. Construction of the bridge was completed on June 14, 2007, and an opening ceremony was held on June 26, 2007 to great domestic media fanfare. But the bridge was not opened to public use until May 1, 2008 after a considerable period of testing and evaluation. The bridge shortened the highway travel distance between Ningbo and Shanghai by 120 km (75 mi) from 400 km (249 mi) and reduced travel time from 4 to 2.5 hours.
