Project: Micangshan Tunnel of BaShan Expressway

The Sichuan section of the Bashan Expressway (Micangshan Tunnel) has a total length of 13.8 kilometers, making it the second longest highway tunnel in China and the third longest in the world. The Micangshan Tunnel passes through the provinces of Sichuan and Shaanxi, separated by a mountain and with vastly different climates. In winter, when entering the tunnel from the Sichuan end, the road surface is normal, but when exiting the tunnel, it is icy and snowy, and the temperature inside the tunnel is also completely different.

The project was officially opened to traffic at 10:00 am on November 22, 2018.

The ChuangDi provides tunnel LED indicator equipment for this project. Since 2018, our equipment has been operating stably and well, with a low repair rate.
