Types of Roads in China

In China, roads are classified into various types based on their function, capacity, and level of development. The main types of roads in China include:

National Highways (Gao Su Gong Lu): These are major highways that connect cities and regions across the country. National highways are numbered with prefixes “G” and are typically four-lane or more expressways with controlled access.
Provincial Highways (Sheng Dao): Provincial highways serve as important transportation links within individual provinces or regions. They are generally well-maintained roads connecting cities, towns, and rural areas.
County Highways (Xian Dao): County highways primarily serve transportation needs within counties or rural areas. They connect towns, villages, and agricultural areas to larger cities and regional centers.
Township Roads (Xiang Dao): Township roads are smaller roads that connect townships and villages within a county or administrative division. They provide local access to rural areas and agricultural land.
Expressways (Gao Su Gong Lu): Expressways are high-speed, limited-access highways designed for long-distance travel and freight transportation. They are typically toll roads and have controlled access with interchanges and overpasses.
Urban Roads (Cheng Shi Dao Lu): Urban roads are roads within cities and urban areas. They include major arterial roads, collector roads, and local streets that provide access to residential, commercial, and industrial areas.
Rural Roads (Nong Cun Dao Lu): Rural roads serve rural areas and agricultural regions. They include unpaved roads, farm roads, and local access roads that connect farms, villages, and rural communities.
Ring Roads (Huan Dao Lu): Ring roads are circular or semicircular roads that encircle major cities to facilitate traffic flow and reduce congestion. They often connect to radial highways and expressways.
