Passage

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.^{[clarification needed]} 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.^{[clarification needed]}

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]
