National routes (South Africa)

Map of National Routes.

National routes in South Africa are a class of 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 maintained by the South African National Roads Agency (SANRAL), but some are maintained by provincial or local road authorities.

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.

Definition

National routes are defined and numbered by the Route Numbering and Road Traffic Signs Sub Committee within the Roads Co-ordinating Body,[1] an organisation which contains representatives from road authorities in national, provincial and local government. The term "national road" is frequently used to refer to a national route, but technically a "national road" is any road maintained by the South African National Roads Agency (SANRAL) and need not necessarily form part of a national route. There are also parts of the national route network that are maintained by provincial or local authorities rather than SANRAL.[2]

List of routes

National Routes are denoted with the letter N followed by a number indicating the specific route. On maps and some signage, national routes are shown by a pentagon with the number of the road inside. There are fifteen declared national routes, which are listed below.[3]

Earlier scheme

An earlier scheme, deviating considerably from the current numbering, is described in the 1970 Shell Road Atlas of South Africa and other contemporaneous sources:
