I was driving through Swindon, which is between London and Bristol, and I arrived at the “Magic Roundabout,” which has been described as the most complicated traffic intersection in the world. Five roads meet here, and five small circles feed a large central one. The traffic direction is clockwise on the small roundabouts, and counter-clockwise on the large one.  The easiest track is just to stay on the outer circle, or you can take a shorter route by heading into the central one. I did that (perhaps unintentionally), and went through with no problem. But then again, I wasn’t in the rush hour. Photo by Dickbauch.

Constructed in 1972, it took on it’s current (popular) name in the 1980s. This mega-roundabout has a good safety record, perhaps because traffic moves so slowly through it. Diagram by Hk ing.

This is not the Magic Roundabout, but it shows how this type of road feature works.

Not everyone loves this junction. Some drivers’ surveys have chosen “The Magic Roundabout” as being amongst the worst intersections in the United Kingdom.

It’s named after a long-running 1960s and 70s French/British children’s TV program.
