List of auxiliary NTHS Expressways

List of the Auxiliary National Trunk Highway System Expressways and List of the Branch National Trunk Highway System Expressways of China. Auxiliary expressways are followed by two additional digits of their primary expressway and the GXX0X series routes are city beltways. Generally, odd-numbered routes have lower numbers in the east and higher numbers in the west; even-numbered routes have lower numbers in the north and higher numbers in the south.

Before 2017, those codes were followed by a cardinal point (N, S, E, W) and an additional digit if repeated starting with 2; associated auxiliary expressways were followed by two additional digits, but during the 13th National People's Congress in 2017, the SAC decided to standardize those branch expressways to use only two additional digits, and therefore all parallel branches and most of city ring routes are having their codes changed.

In this list under Number column, the gray colored routes are not yet completed.
