The north section of the Lhasa ring road, in Tibet, has been put into trial operation. The ring road, built to ease traffic congestion and accelerate the city's development, comprises seven tunnels and 27 bridges and overpasses.
The road links Lhasa Gongkar Airport in the south with three highways, and also crosses the Qinghai-Tibet Railway.
When the whole project is complete in June this year, drivers will be able to circle the city's downtown area in two hours at a maximum speed of 60km per hour.
Construction started in October 2015, and is to be complete in June 2017. The total cost of the project is 11.3 billion yuan, or 1.62 billion US dollars.
