China National Highway 102 is a major trunk route connecting Beijing to Harbin, Heilongjiang. In Beijing it is known as Jingha Road (京哈路), after the two cities' names, for connecting Beijing to Harbin.
It leaves Beijing as the Jingtong Expressway and Tongzhou–Yanjiao Expressway into Hebei Province (they are rare occurrences that sections of National Highways are built to National Expressway standards). It then runs alongside the Beijing–Shenyang Expressway along the coast until Shenyang, Liaoning, and then along the Shenyang–Harbin Expressway until Harbin.
China National Highway 102 is 1,297 km (806 mi) in length. It runs through the provinces of Hebei, Liaoning, Jilin and Heilongjiang. It connects major cities of Qinhuangdao, Shenyang, Changchun and Harbin.
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(East-West 228-248, North-South 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.
