Qingdao, a port city in east China's Shandong Province, is seeking investments for constructing two subsea tunnels in Jiaozhou Bay. Xinshi Industrial Co. Ltd. is the project developer. The tunnels would connect Xuejia Isle of the Huangdao Island District and Tuandao Isle of Qingdao by crossing at the mouth of Jiaozhou Bay. The subsea tunnels, extending some 6,170 m, will have six lanes capable of accommodating vehicles with a speed of 80 km per hour. The project is expected to cost 3.186 billion yuan (about USD400 million). The investment is expected to be recovered in about 11 years. The tunnels are expected to be completed in four years. 02/06.
