Guoliang Tunnel in Taihang mountains (China)

The road Guoliang Tunnel in Taihang mountains (China) has been built by villagers themselves.Before 1972, the path chiseled into the rock used to be the only access linking the village with the outside world. Then the villagers decided to dig a tunnel through the rocky cliff. Led by Shen Mingxin, head of the village, they sold goats and herbs to buy hammers and steel tools. Thirteen strong villagers began the project. It took them five years to finish the 1,200-metre-long tunnel which is about 5 meters high and 4 meters wide. Some of the villagers even gave their lives to it. On May 1, 1977, the tunnel was opened to traffic.
