Qingdao Jiaozhou Bay tunnel is an under-sea road tunnel located in Shandong Province in eastern People's Republic of China. It crosses underneath Jiaozhou Bay, connecting Huangdao to the south with the city of Qingdao in the north (see map), at the narrow entrance to the bay.[3] It starts at Tuandao Road in the north and ends between Beizhuang village and Houchawan village on Xuejia Island in the south.[2]
Construction began on December 27, 2006[4] and was completed five years later when it opened on July 1, 2011, two months after the scheduled opening date. It opened the same day as the nearby Jiaozhou Bay Bridge, considered at the time the world's longest open water bridge by Guinness World Records.[5] The bridge and tunnel were planned together as the Jiaozhou Bay Connection Project.[6]
The length of the tunnel road is 6.17 km (3.83 mi).[6] The tunnel travels underground for 5.55 km (3.45 mi) with a sub-sea portion of 3.3 km (2.1 mi).[2][6][7] There are two tubes of 3-lanes each for a total of 6-lanes.[2]

Thursday also saw the opening of the nation's longest undersea tunnel, also linking downtown Qingdao to Huangdao. The 6.17-km tunnel provides a fast link between the two areas.
