China National Highway
The China National Highways (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) are a series of trunk roads across mainland China. Although they are called "highways" (e.g., the Jingbao Highway), they are not necessarily freeways. However, like expressways, a toll is sometimes charged.
Although an accepted speed limit on China National Highways is 100 km/h, it is common to see cars pass other by in well in excess of 100 km/h. The lack of speed detection cameras on some routes, lack of a posted speed limit outside of localities and tremendous distances of road mileage, means that enforcing this speed limit is rather herculean. In addition there is a notable shortage of traffic police in mainland China.
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:
In major cities, there is usually a gap in the road within the city.
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 has now reached 19.5 km per 100 km2.
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.
