The Primary routes (主线) of National Trunk Highway System Expressways 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. These routes are officially printed in the 2022 National Highway Network Plan.[1]

Primary NTHS Expressways[edit]

Number Name Chinese Name Origin Terminus Length Formed Notes

G3 Jingtai Expressway 京台高速 Beijing, BJ Pingtan, FJ (de facto)
(de jure: Taipei, TW)		 2,030 km (1,260 mi) 2020 (mainland section only) See also Political Status of Taiwan. A theoretical an unbuilt bridge/tunnel way connecting Pingtan, FJ with Taoyuan, TW. Without the Taiwan section it would be otherwise complete. Formerly multiplexed with G2 between Cangzhou and Langfang until current G2 alignment was built.
G4 Jinggang'ao Expressway 京港澳高速 Beijing, BJ port of Hong Kong, HK 2,285 km (1,420 mi) 1996 part of AH1
connects to San Sham Road via Huanggang Port and Lok Ma Chau Control Point.
G5 Jingkun Expressway 京昆高速 Beijing, BJ Kunming, YN 2,865 km (1,780 mi) 2015 By strictly, the first 8.5 km section (from east of Liangtuolu bridge to Dajian Road IC) is S66, though a re-route to Mentougou is considering.
G6 Jingzang Expressway 京藏高速 Beijing, BJ Lhasa, XZ 3,718 km (2,310 mi) 2021 (except Golmud–Nagqu) part of AH3 (between Beijing and Ulanqab) and AH42 (between Lanzhou and Lhasa)
multiplexed with G7 between Bayannur and Beijing in the original plan until the China National Highway 110 traffic jam; still de facto multiplexed between Huailai and Changping due to a freeway gap in G7 (see below).
G7 Jingxin Expressway 京新高速 Beijing, BJ Ürümqi, XJ 2,540 km (1,580 mi) 2021 (except some sections in Beijing, see notes) multiplexed with G6 between Bayannur and Beijing in the original plan until the China National Highway 110 traffic jam. The section between Yuequan Road crossing and Jimen bridge had its build postponed due to Jingzhang intercity railway Qinghuayuan tunnel, and it is unclear as to when its construction will start; between Deshengkou tunnel and Laoyinzhuang junction, only southbound section is opened for freight transport; northbound section of this, and section between Laoyinzhuang and Yanqing East junctions, are also not built, and construction plans are stalled in favor of S3801 Jingli expressway; therefore de facto multiplexed with either G6 or S3801 between Huailai and Changping.
