Mini-roundabout 		2014 All paint, no raised islands. Opened November 2014. Previously, Olympia Park Circle made a gentle 90-degree curve. Traffic entering from stop-controlled driveway had trouble making left turn as they had to proceed 60 feet to reach the safety of centerline without knowing if approaching vehicle on their left was going to enter the driveway or curve left in front of them. Now about 50% of driveway exits cheat across the central island, but it works just fine.
