I have already mentioned in this blog that the Tibetan Autonomous Region’s government has been planned more than 20 new highways (included new routes from Lhasa to Nagchu; Dege to Chamdo; Chamdo to Jaka; Lhasa to Shigatse Airport; and Gongkar Airport to Tsethang) to be constructed next year, with a total investment of more than US$ 5 billion.
More information has now come out.
A 73-kilometers around Lhasa is under construction. Some 4.9 billion yuan has been spent so far on the project and the basic work is completed. According to China Tibet News,the loop-line is expected to be finished by the end of this year. The site says that the project “is meaningful to perfect city traffic network, drive the exploitation and utilization of land around, and reserve space for the urban development in the future.”
It is probably necessary to receive 25 million tourists. [Source]
