The hanging wall road is one of the most distinctive highways. It is a dangerous highway that is cut out on the cliffs. Traffic experts say such projects are rare and difficult, and are rare in the history of China's road construction. In order to facilitate the construction and opening of natural lighting, Wall Road multi wall and chisel, separated by more than ten meters next to open the side of the window. From a distance, the frontline window outlines the direction of the tunnel.
There are seven hanging wall highways in the South Taihang Mountain area in the southeast of Jin Dynasty. Taihang mountain high and low in the south, the East West steep relief, the west wing is connected with the Shanxi plateau, east of the obvious fault, many areas formed nearly 1000 meters of fault rock, imposing. There are many rivers in Taihang Mountain, which are originated or flowed through, causing the continuous mountains to break down and form "water outlets". Most of them are waterfalls due to the fault wall. Only a few of them have smaller slopes. "Water outlet" can become a key way for the North China plain to enter Shanxi plateau. The hanging wall road is built on the fault cliff of the North China plain to the Shanxi plateau.
Lingchuan, Shanxi: Tin cliff hanging wall Road, Chen home wall Road, Kunshan hanging wall road Shanxi flat: Hong ladder wall Road, the bottom of the wall Road

After the leardo highway tunnel in Norway is 24.51 kilometers long.
    It is understood that the Qinling Mountains Zhongnanshan tunnel has created six of the most China Highway Tunnel Construction: the world's first single hole double hole highway tunnel, a total length of 18.02 kilometers; the first to design, construction and supervision by China, and the highest level of comprehensive management, the world largest caliber, the depth of the tunnel; the highest shaft ventilation engineering has the most comprehensive monitoring system; world highway; special highway tunnel lighting the world's most advanced zone; first proposed strategy management theory, using the first strategy of software automatic generation, automatic monitoring and management of fire, traffic accidents, maintenance etc.. In this sense, the technical significance of the Qinling Mountains Zhongnanshan tunnel is not only Shaanxi, but also the world.
    Go from Qinling Mountains Zhongnanshan tunnel north, South 18.2 kilometers across Qinling Mountains can. Qinling Mountains Zhongnanshan tunnel, designed at a speed of 80 kilometers per hour, takes about 15 minutes to complete the journey. In these 15 minutes, you can feel the difference of this tunnel. Different places, different colors of light, in the tunnel form a light world. And more specifically, you can't take a long walk, and you'll see a bright front in front of you, and it seems to be going to the hole. The clouds are in the sky, and the trees are shaded under the ground. The special light belt in the tunnel is 150 meters long and 20.9 meters in width. It is like a small small park in the tunnel.

This particular space forcing the road number of turns, forming 13 sharp sharp, almost parallel, 26 section of pavement under the overlapping. The width of the road is not more than 7 meters, the narrowest section is less than 4 meters, and two cars can not pass at the same time in the narrowest section. It is said that during the construction period, we first cut out a strip of steps on the slope of Dashan, then connected the two ends of the stairs.
