This past Saturday, the OPP had a speed trap setup in the construction zone east of Windsor where the speed limit is reduced to 80. I cannot remember the name of the overpass they were setup at but when the highway is reduced to one lane there is a curve ahead and the first overpass on the curve is where they are stationed at. Best to begin slowing down in the 80 zone and when you "see" the signage ahead signalling the lane reduction (to one lane) ahead make sure you're doing 80-85.
