This article is about the expressway system of the People's Republic of China. For the regular highway system of the People's Republic of China, see China National Highways.
The expressway network of China,with the national-level expressway system officially known as the National Trunk Highway System (Chinese:中国国家干线公路系统;pinyin:ZhōngguóGuójiāGànxiàn GōnglùXìtǒng;abbreviated as NTHS),is an integrated system of national and provincial-level expressways in China.[1][2]
With the construction of the Shenyang–Dalian Expressway beginning between the cities of Shenyang and Dalian on 7 June 1984,the Chinese government started to take an interest in a national expressway system. The first modern at-grade China National Highways is the Shanghai–Jiading Expressway,opened in October 1988.[note 1] The early 1990s saw the start of the country's massive plan to upgrade its network of roads.[1][dead link][3] On 13 January 2005,Zhang Chunxian,China's Minister of Transport introduced the 7918 network,later renamed the 71118 network,composed of a grid of 7 radial expressways from Beijing,9 north–south expressways (increased to 11),and 18 east–west expressways that would form the backbone of the national expressway system.[2][dead link][4]
By the end of 2020,the total length of China's expressway network reached 161,000 kilometres (100,000mi),[5] the world's largest expressway system by length,having surpassed the overall length of the American Interstate Highway System in 2011.[6] Many of the major expressways parallel routes of the older China National Highways.[citation needed] By the end of 2022,the total length of China's expressway network reached 177,000 kilometres (110,000mi).[7] By end of 2023,the total length of China's expressway network reached 184,000 kilometres (114,000mi).[8]
History
Length of National Trunk Highway System by year[9][10]
Prior to the 1980s,freight and passenger transport activities were predominantly achieved by rail transport rather than by road. The 1980s and 1990s saw a growing trend toward roads as a method of transportation and a shift away from rail transport. In 1978,rail transport accounted for 54.4 percent of the total freight movement in China,while road transport only accounted for 2.8 per cent. By 1997,road transport's share of freight movement had increased to 13.8 percent while the railway's share decreased to 34.3 percent. Similarly,road's share of passenger transport increased from 29.9% to 53.3% within the same time period,with railway's share decreasing from 62.7 percent to 35.4 percent. The shift from rail to road can be attributed to the rapid development of the expressway network in China.[1][dead link][citation needed]
Expressways were not present in China until 1988.[11] It began building expressways in the late 1980s.[12]:401 On 7 June 1984,China's expressway ambitions began when construction of the Shenyang–Dalian Expressway began between the cities of Shenyang and Dalian. Due to policy restrictions,the expressway was nominally implemented on the first-grade automobile special highway standard in the initial stage of construction,thus making the highway technically not an expressway. Despite this,in October 1988,four years later,two full-speed,fully enclosed,controlled-accessed expressway sections from Shenyang to Anshan and Dalian to Sanshilipu totaling 131 kilometres (81mi) were completed,with the 108 kilometres (67mi) middle portion of the expressway remaining a highway. It would take until 20 August 1990,for all sections of the highway to become that of an expressway. The expressway is now part of the longer G15 Shenyang–Haikou Expressway.[3][dead link][citation needed]
On 3 September 1998,Huabei Expressway Co.,Ltd.,Northeast Expressway Co.,Ltd.,Hunan Changyong Expressway Co.,Ltd.,and Guangxi Wuzhou Transportation Co.,Ltd. were approved by the government as the first batch of nationally issued stock companies that would develop,construct,and operate expressways in China.[13][14][15]
On 13 January 2005,Zhang Chunxian,China's Minister of Transport announced that China would build a network of 85,000 kilometres (53,000mi) expressways over the next three decades,connecting all provincial capitals and cities with a population of over 200,000 residents. The announcement introduced the 7918 network,a grid of 7 radial expressways from Beijing,9 north–south expressways,and 18 east–west expressways that would form the backbone of the national expressway system.[2][dead link][citation needed] This replaced the earlier proposal for five north–south and seven east–west core routes,proposed in 1992.[1][dead link][citation needed]
In June 2013,the Ministry of Transport introduced the National Highway Network Planning,covering both the national highway system and the national expressway system from 2013 to 2030. Goals include making traffic travel more convenient and developing a variety of regions,as well as more focus to the highways and expressways of the western regions of China. According to this plan,the total size of the national road network will reach 400,000 kilometres (250,000mi),including 265,000 kilometres (165,000mi) of common national highways and about 118,000 kilometres (73,000mi) of expressways. In addition,the 7918 network would be renamed the 71118 network when the number of north–south expressways were increased from 9 to 11. Huang Min,director of the Basic Industry Department of the Development and Reform Commission,said that whether the plan is for ordinary national roads,the development of expressways is prioritized more in the western regions. According to Huang,the two expressways were to be added to the western region,while none in the northern,eastern,or southern regions.[4]
In 2014,Wang Tai,deputy director of the Highway Bureau of the Ministry of Transport,introduced the national toll highway mileage and mainline toll stations.[16]
On 6 November 2015,Hu Zuicai,deputy director of the National Development and Reform Commission,introduced a reform policy for construction of China's expressway system that was approved by the State Council. Hu claimed that the current highway construction is facing problems such as pre-approval and evaluation assessment. Through simplification and integration of examination and approval stages,it will help speed up the pace of highway construction,promote urban development in the region,and help stabilize growth and promote investment. This policy,during the “Thirteenth Five-Year Plan”period,would focus on five aspects:[17]
Speeds up the building of expressways,especially to link the broken roads between the provinces as soon as possible,and to play the overall role of the expressway system;
Supports the three major strategies and strengthen the important domestic and inter-provincial channels of the international economic cooperation corridor,connecting important coastal highways along the coast of the Yangtze River and linking the construction of important port highways;
Serves new urbanization and urban agglomerations,and connecting cities and cities within urban agglomerations between cities and cities is the key to construction;
Supports poverty alleviation and cracks down on poverty by linking between cities and regions;
Efforts are made to improve the efficiency of transportation,so that the freeway and other modes of transport can be seamlessly connected or transferred and the overall transportation efficiency can be improved.
In 2020,all toll booths at provincial borders were abolished in favour of ETC,greatly reducing traffic congestion.[18][19]
In 2022,the NDRC and MOT published a new National Highway Network Plan (Chinese:国家公路网规划),added and re-formed several expressways and national highways. It is expected that all national expressways will connect prefecture-level administrative regions (except Sansha),other cities and counties with 100,000 and more populations,and important border checkpoints.[20]
Safety
In 2008 the rate of fatalities on Chinese expressways is 3.3 fatalities per 100 million vehicle-km. Nonetheless,the fatality rate on Chinese expressways is five times higher than western countries which have a 0.7 rate.[21] In 2010 the total expressway mileage accounted for only 1.85 percent of highway mileage driven,however accidents on expressways made up 13.54% of highway traffic deaths.[22] For the 2011-2015 period this was still at 10%.[23] The accidents are mainly caused by tailgating,fatigue and speeding.[24]
Neither officially named "motorway" nor "highway",China used to call these roads "freeways". In this sense,the word "free" means that the traffic is free-flowing;that is,cross traffic is grade separated and the traffic on the freeway is not impeded by traffic control devices like traffic lights and stop signs. Some time in the 1990s,"expressways" became the standardised term.
"Express routes" exist too;they are akin to expressways but are mainly inside cities. The "express route" name is a derivation of the Chinese name kuaisu gonglu (compare with expressway,gaosu gonglu). Officially,"expressway" is used for both expressways and express routes,which is also the standard used here.
The names of the individual expressways are regularly composed of two characters representing start and end of expressway,e.g. "Jingcheng" expressway is the expressway between "Jing" (meaning Beijing) and Chengde.
A minimum speed limit of 60km/h (37mph) is in force. On overtaking lanes,however,this could be as high as 110km/h (68mph).[25] Penalties for driving both below and in excess of the prescribed speed limits are enforced.
Some expressways have a lower design speed of 80 kilometres per hour (50mph).[26]
Legislation
Only motor vehicles are allowed to enter expressways. As of 1 May 2004,"new drivers" (i.e.,those with a Chinese driver's licence for less than a year) are allowed on expressways,something that was prohibited from the mid-1990s.
Overtaking on the right,speeding,and illegal use of the emergency belt (or hard shoulder) cost violators stiff penalties.
The signs on Chinese expressways use white lettering on a green background,like Japanese highways,Italian autostrade,Swiss autobahns and United States freeways. Newer signage places the exit number in an exit tab to the upper right of the sign,making them very similar in appearance to American freeway signs.
Exits are well indicated,with signs far ahead of exits. There are frequent signs that announce the next three exits. At each exit,there is a sign with the distance to the next exit. Exit signs are also posted 3,000m (9,800ft),2,000m (6,600ft),1,000m (3,300ft),and 500m (1,600ft) ahead of the exit,immediately before the exit,and at the exit itself.
Service areas and refreshment areas are standard on some of the older,more established expressways,and are expanding in number. Gas stations are frequent.
Signs indicate exits,toll gates,service/refreshment areas,intersections,and also warn about keeping a fair distance apart. "Distance checks" are commonplace;the idea here is to keep the two-second rule (or,as Chinese law requires,at least a 100m (330ft) distance between cars). Speed checks and speed traps are often signposted (in fact,on the Jingshen Expressway in the Beijing section,even the cameras have a warning sign above them),but some may just be scarecrow signs. Signs urging drivers to slow down,warning about hilly terrain,banning driving in emergency lanes,or about different road surfaces are also present. Also appearing from time to time are signs signaling the overtaking lane (which legally should only be used to pass other cars). Although most English signs are comprehensible,occasionally the English is garbled.
Many expressways have digital displays. These displays may advise against speeding,indicate upcoming road construction,warn of traffic jams,or alert drivers to rain. Recommended detours are also signaled. The great majority of messages are only in Chinese.
Exit numbering

Exit numbering has been standardised in China from its inception. Most Chinese expressways,especially those in the national network,use distance-based exit numbering,with the last three numbers before the decimal point taken used as the exit number. Hence,an exit at km 982.7 would be Exit 982,whereas an exit at km 3,121.2 would be Exit 121. Exit numbers on Chinese expressways increase along the total length of the freeway,regardless of how many provincial boundaries the expressway crosses.[27]
Some,mostly regional,expressways still use sequential exit numbering,although even here,new signage feature distance-based exit numbering. Before the 2009–2010 numbering switchover,nearly all of China's expressways used sequential numbering,and a few expressways used Chinese names outright.
One of the reasons for this shift is that distance-based exit numbering comes in handy when newly built exits are added to an expressway exit system. If sequential numbering is used,numbers of all the exits following the new exit have to be replaced,which will be a troublesome and costly project. But that will not be a problem for distance-based exit numbering.
The exit is written inside an oval in green letters to the immediate right of the Chinese word for exit,"出口" (chukou).

Costs
The total costs of the national expressway network are estimated to be 2 trillion yuan (some US$300 billion as rate in 2016). From 2005 to 2010, the annual investment was planned to run from 140 billion to 150 billion yuan (17 to 18 billion U.S. dollars), while from 2010 to 2020, the annual investment planned is to be around 100 billion yuan.[citation needed]
The construction fund will come from vehicle purchase tax, fees and taxes collected by local governments, state bonds, domestic investment and foreign investment. Unlike other freeway systems, almost all of the roads on the NTHS/"7918 Network" are toll roads that are largely financed by private companies under contract from provincial governments. The private companies raise money through bond and stock offerings and recover money through tolls. Examples of these companies include Huabei Expressway Co., Ltd., Northeast Expressway Co., Ltd., Hunan Changyong Expressway Co., Ltd., and Guangxi Wuzhou Transportation Co., Ltd.[13][14][15]
China has an extensive tollway system, which composed of nearly all expressways as well as having around 70% of the world's tollways.[30] Tolls are roughly around CNY 0.5 per kilometer, and minimum rates (e.g. CNY 5) usually apply regardless of distance. However, some are more expensive (the Jinji Expressway costs around CNY 0.66 per kilometer) and some are less expensive (the Jingshi Expressway in Beijing costs around CNY 0.33 per kilometer). It is noteworthy that cheaper expressways do not necessarily mean poorer roads or a greater risk of traffic congestion.[citation needed]
Roads in Tibet and Hainan are all toll free. In Tibet, this is done to stimulate economic development, whereas in Hainan, the cost is covered by a provincial fuel tax, first instated in 1994.[31][32] Tolls are waived nationwide during national holidays, such as Golden Week, and regionally for locally observed holidays. For example, Xinjiang makes all expressway travel free during Eid al-Fitr and Eid al-Adha.
Expressway planning is performed by the Ministry of Transport of the People's Republic of China. Unlike the road networks in most nations, most Chinese expressways are not directly owned by the state, but rather are owned by for-profit corporations (which have varying amounts of public and private ownership) which borrow money from banks or securities markets based on revenue from projected tollways. Examples of these corporations include Huabei Expressway Co., Ltd., Northeast Expressway Co., Ltd., Hunan Changyong Expressway Co., Ltd., and Guangxi Wuzhou Transportation Co., Ltd.[13][14][15] One reason for this is that Chinese provinces, which are responsible for road building, have extremely limited powers to tax and even fewer powers to borrow.[citation needed]
China's tollways were criticized for having excessively high toll fees.[30] According to Zhongxin.com, by reducing toll fees, it will lead to logistic costs reductions, another problem encountered by the country's expressway system.[33] Reforms of the tollway system were planned by the National People's Congress with the inclusion of cost reduction of bridges.[34]
However, the toll system was also praised by the World Bank for encouraging construction/maintenance, discouraging overuse, and not unduly favouring roads over other forms of transportation like rail.[35]
Methods
Most expressways use a card system. Upon entrance to an expressway (or to a toll portion of the expressway), an entry card is handed over to the driver. The tolls to be paid are determined from the distance traveled when the driver hands the entry card back to the exit toll gate upon leaving the expressway. A small number of expressways do not use a card system but charge unitary fares. Passage through these expressways is relatively faster but it is economically less advantageous. An example of such an expressway would be the Jingtong Expressway.[36]
China is increasingly deploying a network of electronic toll collection (ETC) systems, and in the latest edition of expressway toll gate signage, a new ETC sign is now shown at an increasing number of toll gates. ETC networks based around Beijing,[37] Shanghai,[38] and Guangdong province[39] all feature either mixed toll passages supporting toll card payment or full-service dedicated ETC lanes. Beijing, in particular, has a dedicated ETC lane at almost all toll gates.[40] By 2019, 90% of traffic paid is expected to pay toll fees using the ETC system.[41]
City transit cards are not widely used; one of the first experiments with the Beijing Yikatong Card on what is now the Jingzang Expressway (G6)[42] went live for only a year before a new national standard replaced it in early 2008.[citation needed]
A previous system, the 1992 "five vertical + seven horizontal expressways" system, was used for arterial expressways and were, in essence, G0-series expressways (e.g. G020, G025). This was replaced by the present-day new numeric system (see below).
New numbering system
A new system, which dates from 2004 and began use on a nationwide level between late 2009 and early 2010, integrates itself into the present-day G-series number system. The present-day network announced in 2017, termed the 7, 11, 18 Network (also known as the National Trunk Highway System, NTHS), uses one, two or four digits in the G-series numbering system, leaving three-figured G roads as the China National Highways.
The new 7, 11, 18 Network is composed of
7 radial expressways leaving Beijing (G1-G7)
11 vertical expressways going north to south (double digit G roads with numbers ending in an odd numeral)
18 horizontal expressways head west to east (double digit G roads with numbers ending in an even numeral)
The network is additionally composed of connection expressways as well as regional and metropolitan ring expressways.
On a nationwide basis, expressways use the G prefix (short for "guojia" in Chinese meaning "national"), as well as the character "国家高速" (National Expressway, white letters on a red stripe on top of the sign). For regional expressways, the prefix S (short for "shengji" or "provincial") is used instead, as well as the one-character abbreviation of the province and "高速" (expressway, black letters on an orange-yellow stripe on top of the sign.) The same numbering system is used for both national and regional expressways.
All expressways in this network begin with the letter G. (For regional expressways, the letter S is used instead.)
All expressways have a thin band on top of the sign. For national expressways, it will be red; for regional ones, it will be orange-yellow.
For radial expressways leaving from or ending in Beijing, use a single digit from 1 to 9 (e.g., G1, G2).
For north–south expressways, use an odd number from 11 to 89 (e.g., G11, G35).
For west–east expressways, use an even number from 10 to 90 (e.g., G20, G36).
For regional ring expressways in the 7, 11, 18 network, use numbers from 91 to 98. (e.g., G91, G93)
For metropolitan area ring expressways, use number 99 plus numbers from 01 to 12. (e.g., G9901, G9912)
Note: G99 or the Taiwan Ring Expressway was a planned expressway based in Taiwan Province before cancelled in 2022, which is claimed by the People's Republic of China, but is actually administered by the Republic of China. (In addition, the ROC has not built the eastern half as an expressway.) See Political status of Taiwan. See also Highway system in Taiwan for the current Republic of China-maintained Taiwan freeway system, which uses a different numbering system.
For city ring expressways, use "0" plus an order number after the main line number, starting from the smallest possible number (e.g., G5001).
For connection expressways, use an odd numeral plus an order number after the main line (e.g., G9411).
For the parallel expressways running alongside primary ones, use an even numeral (except "0") plus an order number after the main line (e.g. G0422, here the corresponding main line with a single digit should follow a "0" to distinguish from CNH).
↑ The Shanghai–Jiading Expressway was the first expressway to be built in Mainland China, excluding Taiwan (see Political status of Taiwan), as well as Hong Kong and Macau, which were under British and Portuguese control respectively at the time. If Taiwan is included, the first expressway to open in modern China was Taiwan's National Highway 1, known as the Zhongshan Expressway, which opened in 1974.

The China National Highways (CNH/Guodao) 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.
Highways in Taiwan are classified into five types:
Expressways in Guangdong are a major form of transportation in Guangdong province. The network consists of national expressways assigned by National Trunk Highway System in China and provincial expressways assigned by Guangdong Expressway system. Expressways in Guangdong usually need a fare of 0.45 CNY/km for a private car due to the provincial standard, while more needed for a larger vehicle. Speed limits also vary with the type of vehicles that usually ranged from 60–120 km/h (37–75 mph).
The Lanzhou South Ring Expressway, designated G2201, is a 58.743-kilometre-long expressway (36.501 mi) that bypasses the built-up area of Lanzhou on the south side, the capital of Gansu Province. The design speed of the road is 80 kilometres per hour (50 mph). Construction started in 2014 and the Expressway was opened on 29 December 2018. The construction cost was budgeted at 11.8 billion yuan.
China National Highway Network Planning (2013–2030) is a plan by the Chinese Ministry of Transport to significantly expand the China National Highways network. The plan calls for the construction of 50,000 kilometres (31,000 mi) of Expressways and 160,000 kilometres (99,000 mi) of toll-free trunk highways. The expansion plans to connect every county in China by national trunk highway, and every city with a population over 200,000 by expressway. At the publication of the plans in 2013, there were still 18 such cities that lacked an expressway connection, as well as over 900 counties not connected by trunk highways. The cost of the plan is estimated at 4.7 trillion yuan.
