Responsibility for the road network differs between trunk and non-trunk routes.
[2] In the 18th and 19th centuries, the Ashanti Empire constructed a complex network of roads to link Kumasi with their territories in modern Ghana.
This category of roads is designated with the letter N followed by a number indicating the specific route.
Designation as a Regional route does not imply that a road is maintained by a regional authority; some parts of the Regional route network are maintained by the Ghana Highway Authority, and parts in cities and towns may be ordinary streets maintained by the Department of Urban Roads and the Department of Feeder Roads.
Regional routes vary in quality and size from dirt roads to multi-lane paved highways.
They serve as feeder roads connecting smaller towns to the national and major regional route network.
