Centerville Police sit on the side street to the west of St Rt 48/S. Main st. In between Edenhurst and Bristol Dr. Usually there midday every weekday, but can be there any time at all. It is easy to go over 35 on this road as it is 4 lanes divided. It can be difficult to see the police because they sometimes hide behind the trees. They generally wont get you for 35-45, but I see cars get nailed for going over that all the time.
