China's longest under-lake tunnel opens

Three LED variable landscape belts have been alternately arranged atop the entire tunnel to emulate a starry sky and reduce fatigue among drivers.

The tunnel is considered the most critical node project of the Suzhou-Wuxi-Changzhou South Expressway, the second expressway between Shanghai and Nanjing. It was built by CCCC Third Harbor Engineering and China Tiesiju Civil Engineering Group.

The Changzhou-Wuxi section of the Suzhou-Wuxi-Changzhou South Expressway starts from the Qianhuang hub in Wujin district, Changzhou, passes through Mashan in Wuxi to the southeast and Meiliang Lake of Taihu Lake, and finally reaches the Nanquan hub to connect with the Around Taihu Expressway. The Changzhou-Wuxi section measures 43.9 km in length, of which 22.43 km lies in Wuxi.
