A beltway (American English), ring road or orbital motorway (British English) is a circumferential highway found around many cities. Often it originally enclosed the built up area and was later encroached upon by developed areas - and some cities have proposed or built second and even third beltways. In the United States, many beltways are part of the Interstate highway system. The concept of a ring road also includes a road in the downtown area, distributing traffic and keeping it from the very center.

The main purpose of beltways is deflecting some traffic from the center of the city.
