The Chinese expressway system is built in a national grid, with the addition of seven radial routes of Beijing: G1 to G7.
G7 is the newest addition, originally there were six radial routes. G7 runs from Beijing to Ürümqi and is also called the Jingxin Expressway (Beijing - Xinjiang Expressway).
An 1,100 kilometer stretch of expressway opened simultaneously in 2017 between Bayannur, Inner Mongolia and Kumul, Xinjiang. This is the longest single highway opening ever in the world.
This stretch runs through extremely remote terrain in western Inner Mongolia, northern Gansu and eastern Xinjiang, with no historic road preceding it, so it only made sense to open it in its entirety as it would otherwise go nowhere. G7 traverses isolated desert and mountain ranges, just south of Mongolia.
Here are some photos of this stretch of expressway. I wonder what the traffic volumes are, I doubt if it is more than 1,000 vehicles per day, maybe even less.
