Main Page | See live article | Alphabetical index 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.
