Ghana Road Network
Roads in Ghana form a network of varied quality and capacity. Responsibility for the road network differs between trunk and non-trunk routes. Trunk roads, which are the most important roads, are administered by the Ghana Highway Authority, which was established in 1974 to develop the trunk road network. Ghana's 13,367 km of trunk roads accounts for 33% of the total road network of 40,186 km. The Department of Feeder Roads is responsible for the construction and maintenance of feeder roads in Ghana, while responsibility for urban roads lies with the Department of Urban Roads.
Road distances are shown in kilometers and Ghana speed limits are indicated in kilometers per hour. Generally, speed limits range from in urban areas, on Regional and Inter-Regional highways, on National highways and on motorways.
Classification
Trunk roads in Ghana are classified as N for National routes, R for Regional routes, and IR for Inter-Regional routes. Each road is given a number which is combined with the prefix, for example N1, R40 and IR11, although their informal or traditional names may still be used or heard occasionally: for instance the Accra - Kumasi Road.National routes
National routes in Ghana are a class of roads and highways that form the trunk routes between major urban centers. Together, they form the backbone of the road system. This category of roads is designated with the letter N followed by a number indicating the specific route. Odd-numbered routes run east to west, while even-numbered routes run north to south.List of routes

Inter-regional routes
Inter-Regional routes, designated with the prefix IR, connect major settlements and regional capitals across regional borders. Running east to west are odd-numbered routes, while north-south routes are even-numbered.List of routes

Regional routes
Regional routes are a mix of primary and secondary routes that link major settlements and serve as feeder roads to the National route network. Major regional routes are designated with the letter R followed by a two-digit number, while Minor regional routes are designated with the letter R followed by a three-digit number.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.
Major regional routes
Major regional routes are the second category of road in the Ghana trunk road network. They serve as feeder roads to the national route network, and are the primary trunk roads in areas where there is no national route.List of routes
