China National Highway 101 is a major trunk route connecting Beijing to Shenyang, Liaoning. In Beijing it is known as Jingshun Road (Chinese: 京顺路) or Jingmi Road (Chinese: 京密路) for connecting central Beijing to Shunyi District and Miyun District, although the actual road goes far beyond these two locations.
China National Highway 112 runs around Beijing
Before 2013, Mainland China observed National Highway 228 as Taiwan Ring, composed of several National Expressway (Republic of China) and Taiwan provincial highways, this designation is not recognized by Republic of China (Taiwan). This observation was eventually dropped in new National Highway plans, replaced by Dandong-Dongxing Highway.
A extension plan of the highway system was announced in 2013, including extension of existing highways(101-112, 201-227, 301-330) and new highways (North-South 228-248, East-West 331-361, Connections 501-581). Only small portions of them needs to be constructed from scratch; most of the new highways would be upgraded provincial/county highways.
Another extension plan was announced in 2022, including new small purpose connection highways (601-701).
