China National Highway 110

China National Highway 110 (G110) runs from Beijing to Qingtongxia, via Hohhot, Baotou in Inner Mongolia, and Yinchuan.

Description
It heads northwest from Beijing to Zhangjiakou then heads straight west, and runs to approximately 1,100 km.

In October 2004 and November 2004, it was overwhelmed with traffic diverted from the Jingzhang Expressway, occurring as a result of a massive traffic jam on the expressway. In a related incident in August 2010, a 100-km traffic jam occurred on this route.

In 2013, under a new 2013-2030 plan by the National Development and Reform Commission and the Ministry of Transport, the G110 has been extended to Qingtongxia.

Main cause of traffic jams
Slow moving traffic and recurrent traffic jams on Highway 110 between Beijing and Inner Mongolia result from an overload of coal trucks transporting coal from newly opened mines in Inner Mongolia to sea ports on the coast of China.
