RetroFest is a time of fun, food, and fast cars, but it could also mean traffic jams.
Chatham-Kent Police are asking everyone to slow down, especially around the classic cars.
Over 700 classic machines will be on display in the downtown core of Chatham.
With the Parry Bridge on Keil Drive restricted to one lane and RetroFest in full swing, there will be traffic jams.
The Royal Canadian Legion will also be having a Decoration Day Memorial Service Parade on Sunday from 1 pm to 3 pm, which may increase traffic in the area.
Maple Drive in Chatham will be closed at the Maple Leaf Cemetery.
