G6 Beijing–Lhasa Expressway

G6 Expressway at the interchange with the Fifth Ring Road in northern Beijing.

Beginning from Beijing and driving southwest to Lhasa, The expressway runs approximately 3,710 kilometres (2,310 miles) through Hebei, Inner Mongolia, Ningxia, Gansu and Qinghai, for a total of seven provincial-level divisions. Excluding the two terminal points, it passes through the major cities of Zhangjiakou, Jining District, Hohhot, Bayannur, Wuhai, Yinchuan, Wuzhong, Baiyin, Lanzhou, Xining and Golmud.

As of August 2010, just over fifty percent of the expressway is open to traffic, which mainly comprises the stretch between Beijing and Xining. Like China National Highway 109 and the Qingzang railway, it is expected to pass west through Golmud before heading southwest into Tibet and Lhasa. Because of climatic conditions, this stretch of the expressway does not yet have a construction timetable.[2]

As of 2019 the expressway is completed between Beijing and Golmud, and the section between Nagqu and Lhasa has completed in August 2021. The mountainous section between Golmud and Nagqu is not yet shown on maps, and reserved for future plans.

The G6 merges with the G7 in Huhhot and does not split until Linhe (now Baynnur).
