After floating on the sea for 16 hours, the second immersive tube of the Dalian bay undersea tunnel was connected to the first immersive tube on March 9, making a progress on construction of the first cross-sea tunnel in northern China.

Invested and undertaken by CCCC, the 5.1-km Dalian bay undersea tunnel involves installation of 18 immersive tubes.

The undersea tunnel is an essential project concerning people’s wellbeing and the revitalization of old industrial bases in northeast China and will greatly relieve the heavy traffic congestion from north to south of Dalian.
