As an important node project, Tudiling Tunnel has a total length of 21.38m and is designed as a double slope tunnel. The entrances and exits are all end wall type, with a design speed of 40km/h, a width limit of 9.0m and a height limit of 5m. The project cost is about 78 million yuan.
The entrance of Tuziling Tunnel is located in Liu Lihong Formation at the foot of Tuziling in Taizimiao Village, Luoerling Town, and the exit is located in Yangshugou Formation in Xinpugou Village, Manshuihe Town, which collides with Jinzhongshui.

After hundreds of days of fighting day and night, the construction unit has overcome difficulties such as complex geological conditions, narrow construction site and tight supply of raw materials. The tunnel project was officially completed in September 16.
The construction of the tunnel will reduce the elevation by 98 meters and shorten the road mileage by about 3 kilometers, which means that the travel time to Daoshichong, Shuiman, Wuhan, Tiantangzhai and other directions will be greatly shortened after the completion of the whole tunnel project, especially to solve the bottleneck restriction of large slope and blocked rain and snow in winter, and completely open up a broad road for poverty alleviation and green development. ...
