Video shows the Mila Mountain Tunnel, a highway tunnel with highest elevation in the world, which is under construction in China’s Tibet. The tunnel is located at the junction of Lhasa and Nyingchi in the Tibet autonomous region at an average altitude of 4,740 meters above sea level. In order to improve local transportation situation, several thousands of constructions workers have been engaging in the Mila Mount Tunnel Project for almost three years.
