A , '''loop''', ( American English ), '''ring road''' or '''orbital motorway''' ( British English ) is a Circumferential Highway found around or within many cities.
''Beltway'', ''orbital motorway'', ''perimeter loop'', ''beltline'', and similar terms refer to an Expressway / Motorway / Freeway style standard road that often originally enclosed the built up area and was later encroached upon by developed areas.
''Ring road'' may sometimes refer to a beltway-style road, but more commonly indicates a road or series of roads within a city or town that have been joined together by Town Planner s to form an orbital distributor style road, but where the standard of road could be anything from an ordinary city street up to an expressway level. The principal difference is that a ring road is an orbital distributor road system designed from already existing roads, as opposed to a beltway which is designed from new as such a road system. A ring road designation also implies a more inner-city road designed to route traffic around a city centre, as opposed to routing traffic around a larger Conurbation .
Some cities have proposed or built multiple concentric beltways and/or ring roads.
Many beltway-style roads are part of a wider highway system, for example in the United States beltways are commonly a part of an Interstate Highway system. Inner/Outer Labeling is a common way of uniformly signing the directions of travel on beltways in America.
In the United States, also has a political connotation (e.g., politics Inside The Beltway ), derived Metonymically from the Capital Beltway encircling Washington, D.C.
South Africa has the most advanced road system of any African country. Most of the major cities' ring roads were built in the 1970s. Well constructed, they are on par with the best in the Western world.

- (''Ring 0''), a conceptual approach to routing traffic away from the very center of the city, to develop greater pedestrian access areas in the center, the so-called "carless center". Though this is the least legitimate in the sense of what is commonly thought as a ring road, merely consisting of ways to route traffic, it differs from the other ring roads in that it would consist of a fully circular network of routes around a focal point, rather than I, II and III, which are properly only semicircular, being as they are, limited by the sea on one side.
