The Primary NTHS Expressways (Chinese: 中国国家高速公路网主线) of China are numbered with one- or two-digit designations. Generally, one-digit routes radiate from Beijing, for two-digit routes, odd-numbered routes under 90 run north-south, with lower numbers in the east and higher numbers in the west; even-numbered routes under 90 run east-west, with lower numbers in the north and higher numbers in the south; while 9X routes are zonal beltways.

Their associated branch expressways are using four-digit designations, with the first two digits selected from this list, see the separate linked list for details.

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