Theprimary routes (主线) ofNational Trunk Highway System expressways ofChina 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.
Theirassociated 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. These routes are officially printed in the 2022 National Highway Network Plan.[1]
