Surrounding almost every major city in the world is a circle or ring of highways that facilitate the flow of traffic. Some are called beltways, others traffic rings, or whatever. They are intersected by roads which go to the very heart of the city and, of course, lead away from it in the opposite direction. They serve a function and purpose, allowing people to move back and forth without having to go through the heart of the city or going very far away from it at the same time.
