This aerial drone photo taken today shows an exterior view of Tianshan Shengli Tunnel on Urumqi-Yuli Expressway in northwest China's Xinjiang Uygur Autonomous Region. The 22.13-km Tianshan Shengli Tunnel, the world's longest expressway tunnel, officially opened to traffic today.
Traversing Xinjiang's central Tianshan Mountains, the tunnel slashes what was once a several-hour mountain drive to just 20 minutes. As a vital artery linking city clusters in northern and southern Xinjiang, the G0711 Urumqi-Yuli Expressway, including the tunnel, also entered operation today. - Xinhua
