The China National Highways (CNH/Guodao) is a network of trunk roads across mainland China. Apart from the expressways of China that are planned and constructed later, most of the CNH are not controlled-access highways.

A trunk road, trunk highway, or strategic road is a major road, usually connecting two or more cities, ports, airports and other places, which is the recommended route for long-distance and freight traffic. Many trunk roads have segregated lanes in a dual carriageway, or are of motorway standard.
