Jefferson just west of Ogden Ave. all the way into downtown Naperville. Jefferson Ave. is covered pretty regularly by radar. It’s hard to slow down here because you either just came off Ogden or crossed Ogden on Jefferson at 40 or 45 and the speed limit suddenly drops to 25 mph residential. I got caught not paying attention to the speed change just before Will o Way Park by a squad car hiding on the side street (Waterford Ct.)on the leFort I’ve also seen them hiding further east off Jefferson between the River Rd stop sign and the Firemen’s Memorial Bridge. They are pretty strict here (still 25 mph). There is no talking your way out. You are better off heading westbound on Aurora right in front of the police station. The speed limit is higher and there is no trap.
