Opened November 2014. Previously, Olympia Park Circle made a gentle 90-degree curve.

Now about 50% of driveway exits cheat across the central island, but it works just fine. After six years with no raised islands, a central island was built on 3 Nov 2020: 20 feet in diameter, 4 inches high, designed for asphalt but built with PCC.
