Chinese media reported China's longest underwater Taihu highway tunnel is set to be open to traffic before the end of the year. The 10.8-km-long, 43.6-meter-wide tunnel is under Taihu Lake, China's third-largest freshwater lake. It is part of the Changzhou-Wuxi Highway which has a total length of 43.9 km. Construction of the underwater tunnel began in January 2018 in east China's Jiangsu Province. The tunnel is expected to go through further processes like pouring concrete and building lake island facilities this year.

China Communications Construction Company’s Third Harbor Engineering Co Ltd’s project manager told Xinhua news agency that the tunnel floor had been completed. He added that the project is using automatic steel processing equipment and intelligent systems that could ensure zero discharge of sewage and dust into the lake.

The road is part of a USD 2.4 billion, 44km highway in Jiangsu Province that will link the city of Wuxi, on the north shore of the lake, with Changzhou.

Lake Taihu, which supplies water to around 30 million people, has suffered severe pollution over the past 40 years, including blooms of poisonous algae, and has been the subject of repeated campaigns by the provincial government to end the dumping into it of sewage, garbage, and industrial and animal waste.
