# National highways of China

The China National Highways (CNH/Guodao) (simplified Chinese: 中华人民共和国国道; traditional Chinese: 中華人民共和國國道; pinyin: Zhōnghuá Rénmín Gònghéguó Guódào) is a network of trunk roads across mainland China. Established to facilitate transportation and economic development, the system includes north-south and east-west arterial highways, expressways, and local roads. By 2024, the network encompasses over 1.9 million kilometers of highways, making it one of the most extensive in the world. Key milestones include the completion of major expressways by 2008 and ongoing expansions to enhance connectivity, especially in western and less developed areas.
Apart from the expressways of China that were planned and constructed later, most of the CNH are not controlled-access highways.

## History

The building of highways is seen as key to accelerating infrastructure construction. In 2003, completed investment in highway construction was 350 billion yuan and 219 key highway projects progressed, focusing mainly on the five north–south and seven east–west national arterial highways as well as highways in western China and in rural areas. By the end of 2004, the total length of highways open to traffic reached 1.871 million km, including 34,300 km (21,300 mi) of expressways up to advanced modern transportation standard, ranking second in the world. The nation's highway density was 19.5 km per 100 km$^2$. With the completion in 2008 of the five north–south and the seven east–west national arterial highways, totaling 35,000 km (22,000 mi), Beijing and Shanghai were linked by major highways, chiefly expressways, to the capitals of all provinces and autonomous regions of China, creating highway connections between over 200 cities.
The aim of the National Expressway Network Plan approved in early 2005 is an expressway system connecting all capitals of provinces and autonomous regions with Beijing and with each other, linking major cities and important counties. The network will have a total length of about 85,000 km (53,000 mi), including seven originating in Beijing; the Beijing-Shanghai, Beijing-Taipei, Beijing-Hong Kong-Macau, Beijing-Kunming, Beijing-Lhasa, Beijing-Ürümqi, and Beijing-Harbin expressways. Half of the projects are already completed.
In 2013 the Ministry of Transport announced the "National Highway Network Planning (2013 - 2030)", which will bring the total number of highways to 119, with 81 connecting highways between them. The total mileage will be increased to 265,000 km (165,000 mi), with increased focus on the western and less developed regions.
In 2022, the NDRC and MOT published a new National Highway Network Plan (Chinese: 国家公路网规划), which added and re-formed several expressways and national highways. The plan aims for all national highways to connect all county-level (or above) administrative regions (except those that are parts of Sansha), important national tourist attractions, and border checkpoints.

## Regulation

The speed limit on China National Highways is 80 km/h (50 mph), on sections with more than one lane per direction it may be up to 110 km/h (68 mph).
Nationwide highways often begin with the letter G, followed by three numerals, e.g.: G107. It is said that the G stands for 国家 (guójiā), or national.
The numbering of the highways is as follows:
* Five vertical and seven horizontal main routes were labelled in the former 000 series (the so-called "five downs and seven acrosses"), although these have been deprecated in favour of the "NTHS" (7, 11, 18) system.
* Highways in the 100 series (e.g. 102, 106) begin from Beijing - the capital city of the People's Republic of China - and spread out in all compass directions, except for China National Highway 112, which originates in Bazhou as it is a ring road around Jingjinji.
* Highways in the 200 series stretch from north to south (e.g., from Hohhot in Inner Mongolia through to Beihai in Guangxi province);
* Highways in the 300 series stretch from east to west (e.g., from Shanghai through to Ruili in Yunnan province);
* Highways in the 500, 600 and 700 series are connecting roads between other national highways.
In major cities, there is usually a gap in the road within the city.

## List of all China National Highways
### Former 000 Series

Note: 000 Series China National Highways pointed to five specific vertical routes, as well as seven specific horizontal routes. Routes ending in "0" were north–south (vertical) routes; routes ending in "5" were east–west (horizontal) routes. The new system with two to four numbers that indicate the "NTHS" (7918) system is now in use instead of the 000 Series. For the expressways named under the new numbering system, see Expressways of China.
It seems that the old 0xx numbers are still signposted using the format GZXX, e.g. in the Qinghai province, there are signs at the G109 (old G025) showing the number GZ25.
