From Roader's Digest: The SABRE Wiki
A Magic Gyratory is a junction that is functionally identical to a Magic Roundabout, but differs in that it is a ring of standard roundabouts, connected by lengths of roadway. As such, they are much larger than a Magic Roundabout.
It is also less confusing to drivers than a Magic Roundabout, and indeed drivers may not be aware that there is anything unusual about the junction.
Magic Gyratories can be found at the following locations:
- Churchbridge, Staffordshire (modified variant)
- Denham Roundabout, Buckinghamshire
- Sadlers Farm, Essex
- The Egg, Tamworth, Staffordshire
