For an at-grade intersection of multi-lane roads, the "Turborotonde" (Dutch language Wikipedia article) or "Turboplein" (Dutch language wegenwiki article) is an alternative to the multi-lane roundabout:

Both examples have exactly four exits. In principle, I can imagine that such a design can be extended to more than four exits. Are there any examples of a turborotonde or turboplein design with more than four exits? What would it look like?
