The Mount Erlang Tunnel is a road tunnel along Sichuan-Tibet Highway, which connects China's Sichuan Province and Tibet Autonomous Region. The tunnel is 8,596 meters long and was dug through Mount Erlang in Sichuan Province.
It opened on December 8, 1999. Construction took three years and cost 470 million yuan.
It was built to reduce time and replaces one of the most dangerous parts of the highway, which had frequent accidents because of landslides, rain and foggy weather.
