There is constantly a police officer sitting on the Meramec Bottom Rd overpass on 55. Usually one there and the other sitting on the entrance ramp, far enough back that if you are traveling north bound, you can’t see him until you look in your rear view mirror seeing those red and blue lights coming at you! They are there mostly in the early afternoon, waiting for the Meramec college kids to get out of school. if not there they are sitting on the side of the highway between Meramec Bottom and Butler Hill on 55. It’s tricky to get past them if they are on the ramps, by the time you see them, it’s too late!
