National routes in South Africa are a class of trunk roads and freeways which connect major cities. They form the highest category in the South African route numbering scheme, and are designated with route numbers beginning with "N", from N1 to N18. Most segments of the national route network are officially proclaimed National Roads that are maintained by the South African National Roads Agency (SANRAL), but some segments are maintained by provincial or local road authorities.[1]
The system was mostly built during the 1970s by the National Party government of South Africa, although construction of new roads and repairs of existing stretches continue today. The system was modeled on the United States Interstate Highway network, an idea first brought into effect by US President Dwight D. Eisenhower during the 1950s, based on the German Autobahn, which he experienced when touring Germany after the Second World War.
Although the terms National Road and National Route are sometimes regarded as synonymous, they have distinct meanings, and not all national routes are National Roads, while some "R"-numbered routes are proclaimed National Roads.[1]
