(, Aug04’19) – China said Aug 3 that it had made a huge progress on the mammoth Lhasa-Nyingchi railway project by completing on Aug 2 the construction of a pivotal tunnel on it.

The Bukamu Tunnel, located in Milin (Tibetan: Miling or Manling) County of Nyingchi (Nyingtri) City, is 9,240 metres long with an average elevation of 3,100 meters above the sea level. It is also the 37th tunnel being finished, leaving just 10 tunnels to be completed by the end of the year, reported China’s official Xinhua news agency Aug 3.

The report cited Wang Shucheng, director of the project, as saying that over 3,000 rock bursts were counted during the construction of the tunnel, while the oxygen level inside was merely 19 percent that of the plain areas.

The Lhasa-Nyingchi railway is 435 km long, with 75 percent of it being bridges and tunnels. It is expected to be completed in 2021.
