Original title: The Mi Cang Shan Tunnel of the Ba-Shaanxi Expressway runs through the second longest highway tunnel in China

At 10:20 on the 9th, with a loud noise coming from the depths of Micang Mountain in Nanjiang County, Bazhong City, Sichuan Province, the Micangshan Tunnel, which lasted five years and a total length of 13.8 kilometers, was officially completed.

It is reported that the Micangshan Tunnel is the third largest in the world, the second in China, and the first highway tunnel in Sichuan. The total length of the tunnel is 13.8 kilometers, including 3 kilometers in Shaanxi and 10.8 kilometers in Sichuan. The smooth completion of the entire tunnel provides a guarantee for the completion of the opening of the entire highway at the end of this year. At that time, it will completely change the history of extremely poor traffic over the Micang Mountain. In particular, the situation where traffic is interrupted by heavy snow every winter will never return.
