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).
