List of auxiliary NTHS expressways


This is a combined list of the spur, parallel, metropolitan area ring and city ring routes of 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 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 published a new recommendation national standard GB/T 917-2017, in this standard document, all auxiliary routes are ruled only having two additional digits, and therefore all parallel routes and most of city ring routes are having their codes changed.
China contains large groups of areas that are sparsely populated; expressways in these areas are therefore usually not designated principals, except when connecting provincial capitals with Beijing or part of the Eurasian Land Bridge. However, in plans for 2035 all prefecture-level capitals and an absolute majority of counties must connect to the NTHS network, even in those remote areas, resulting in extremely long branch expressways of the NTHS, including but not limited to G0611, G0612, G0613, G0615, G1013, G1816, G5511. They likely will exceed 1,000 km when completed, while the longest branch Interstate does not exceed 250 km. The G4218 is estimated at 4,000 km and will be the longest spur route in the world when completed.
In this list under number column, the gray colored routes are not yet completed. The routes are officially printed in the 2022 National Highway Network Plan.

City ring expressways

In 2022, some ring expressways of coastal cities were removed due to geographical constraints, along with Lhasa's, due to its extremely rugged and mountainous terrain, and Shenzhen's, probably due to EIA problems regarding Hong Kong Frontier Closed Areas.
