Sichuan Yakang Expressway

a miracle of China's highway construction

Sichuan Yakang Expressway started construction in September 2014. After more than three years of hard work, the Yalong section will be completed and commissioned. The completion of the Yakang Expressway will completely end the history of no-highway in the Tibetan areas of Sichuan.

It is a poverty alleviation channel that supports the poverty alleviation of the Tibetan areas. It is also of great significance for Sichuan to integrate into the “Belt and Road” and promote long-term stability and tourism resources development in Tibetan areas.

The geology and topography along the Yakang Expressway are complex, the mountain is steep, the earthquake intensity is high, landslides, mudslides, collapses, etc. The entire tunnel group is 50 kilometers long, and the longest Erlang Mountain special long tunnel is 13.4 kilometers long. Construction access roads are laid on cliffs, and material transportation, tunnel slag, and power supply are extremely difficult.

On December 31, 2018, the Sichuan Ya (An) Kang (Ding) Expressway, which is known as the high-speed Everest Cloud Road, has a total length of 135 kilometers and has been built for four years.

The altitude difference is more than 1,900 meters, passing through Erlang Mountain and Luding Bridge. Waiting, it is very difficult, created a number of world first, only three and a half hours to complete the journey. It’s really spectacular, and it’s no longer difficult to go to the sky. It’s not easy!
