The completion of the erection of the Baizhen grand bridge also signifies that the paving work of the Lhasa side of the Lhasa-Linzhi Railway has achieved a phased victory.
The 3rd Company of the 11th Bureau of China Railway undertakes the 399.61 kilometers of main rail laying of Lhasa-Linzhi Railway and the prefabrication and erection of 1814-hole T-beams. The railway crosses the Yarlung Tsangpo (Brahmaputra) river 16 times on the whole line.
