Mini-Roundabout FAQs

September 9, 2024 by Julie Swiler

Vehicle enters a mini-roundabout

Increasingly, local agencies are opting for mini-roundabouts for some locations instead of traditional roundabouts, which typically require a larger footprint than a standard four-way intersection. Mini-roundabouts are characterized by a small diameter and fully traversable islands (central island and splitter islands).

The focus of this guidance is to help Minnesota agencies learn more about mini-roundabouts. It defines mini and compact roundabouts and provides selection criteria on when to use them as well as details regarding the center treatment. The FAQ format provides easy navigation to technical information.
