LHASA, June 21 (Xinhua) -- The construction of a major bridge over the Yarlung Zangbo River in southwest China's Tibet Autonomous Region concluded Saturday, marking the completion of all 120 bridges in the 435-km railway linking regional capital Lhasa and Nyingchi.
In early April, all the 47 tunnels on the railway were completed.
The 525.1-meter-long bridge at an altitude of 3,350 meters is the world's highest concrete-filled steel tube arch railway bridge.
Notably, 75 percent of the Lhasa-Nyingchi railway is bridges and tunnels, and it has a designed speed of 160 km per hour. It is expected to be completed and put into operation in 2021. Enditem
