China road numbering
|This article does not cite any references or sources. (December 2009)|
Roads in the People's Republic of China are numbered G, S or X, and four different categories (not including expressways and express routes) exist:
Non-expressways and non-express routes
- G routes stand for Guodao, or China National Highways. These roads often exist to liaise between different centres.
- S routes stand for Shengdao, or provincial roads.
- X routes stand for Xiandao, or county-level roads.
- A rank below them are the xiangdao, or township-level roads.
G, S, and X roads often become city roads as of the delimitation of the city. At the city border, control of the road switches from the gonglu side (public road administration) to the shizheng side (city government).
Expressways and express routes
Expressways of China use a new numbering. The labelling of the former three digit 0-series G routes (e.g. G020) was replaced by a system that uses one digit for expressways starting in Beijing (e.g. G5), two digits for long-distance expressways (e.g. G30) and four digits for regional and local expressways (e.g. G9411).
