Numbering

The national-level expressways are numbered with a letter prefix G, which is short for "guojia" in Chinese meaning "national". For provincial-level expressways, a letter prefix S, which is short for "shengji" (province level). The numbering of provincial-level expressways in Henan follows the rules below:^[3]

• For radial expressways leaving Zhengzhou (the province capital), use a number in 81–90. (except for S1)
• For north–south expressways, use an odd number in 11–59. (in ascending order from east to west, except for S81)
• For east–west expressways, use an even number in 10–60. (in ascending order from north to south, except for S72 and S82)
• For connection or parallel routes, use a number in 61–80, 91–99, except for S38 and S84
• The numerical sequence number of the provincial expressway does not overlap with the numerical sequence number of the national expressway within the province.

On July 8, 2024, the latest version of Henan Expressway numbering was released by Henan Provincial Department of Transportation.^[4]
