A ring road (also known as beltline, beltway, circumferential (high)way, loop or orbital) is a road or a series of connected roads encircling a town or city.
Of particular note is the Vienna Ring Road in Austria, which is the only one in the world to be inscribed by UNESCO as a World Heritage Site.
