Urumqi, Dec. 26 -- The 22.13-km Tianshan Shengli Tunnel, the world's longest expressway tunnel, officially opened to traffic on Friday.
Traversing the central Tianshan Mountains in northwest China's Xinjiang Uygur Autonomous Region, the tunnel slashes what was once a several-hour mountain drive to just 20 minutes.
