China builds world’s highest road tunnel to connect Tibet
China on Thursday completed work on the world’s highest road tunnel costing about USD 170 million on the Sichuan-Tibet highway, which will reduce the time to reach Tibet by two hours. The seven-km-long tunnel, situated 6,168 metre above sea level, passes through the main peak of Chola Mountain.
Reducing the time from Chengdu, capital of Sichuan province, to Nagqu in Tibet by two hours, and avoiding the most dangerous section on the highway. The tunnel, with two lanes in each direction, was under construction since 2012. It will open to traffic next year. The current 40-km precipitous mountain highway in the Tibetan Autonomous Prefecture of Garze takes over two hours to traverse.
