Learn how to drive Georgia's first Diverging Diamond Interchange at a test drive event sponsored by the Perimeter Community Improvement Districts. Drive a golf cart on a simulated track for a "windshield level" experience of the new DDI opening soon at the I-285 and Ashford Dunwoody Road Interchange. The innovative DDI design shifts the flow of traffic to the opposite side of the road to reduce points of traffic conflict. Refreshments, music. Free "Can you DDI?" t-shirts for the first 100 participants. Event is free and open to the public.
