South Africa has the longest road network of any country in Africa with a high standard and extensive road network of about 754 000 kilometres  of which over  70 000km are paved or surfaced roads.

While the Department of Transport is responsible for overall policy, road-building and maintenance is the responsibility of the South African National Roads Agency (Sanral) as well as the nine provinces and local governments.

Sanral is responsible for the country’s network of national roads, which grew to over 20 000km and an estimated value of over R40-billion in 2010. Around 3 000km of the national roads are toll roads. A multi-billion rand freeway improvement scheme has significantly eased congestion on the roads in Gauteng, the province with country’s busiest roads.
