Police officer was apparently on side road with a radar device. Highway 23 was closed to thru traffic and sign directed traffic toward Highway KK. Upon reaching Highway KK, there were no detour signs to direct a driver where to go to regain connection to Highway 23, nor were there any speed limit signs. Upon reaching first road back to Highway 23 and traveling over 3 miles, discovered 23 was still closed to thru traffic despite no construction equipment in sight. Turning around and returning to KK, took next road to return to 23 and concurred the same and turned around again. This occurred two more times before reaching Callan Road where I was stopped by a police officer (Captain) who issued speeding citation. I explained situation and indicated no speed limit signs were noticed. The police officer was the only full time officer in the town’s police department. On the speeding citation, the officer did not indicate the right color of my vehicle. Since I was from out of town, I mailed my fine instead of returning in two months to defend myself and also incur traveling expenses on top of fine issued by a biased judge or jury. This was first time I had even been stopped by the police in 40 years. The GPS coordinates noted on the citation were 43.807813 and -88.793968. A few days later I was traveling in the opposite direction on the same road and I saw the same officer at about the same place in pursuit of another vehicle with his red and blue lights flashing. That was a clear indication to me that this was a normal routine speed trap staged without adequate speed and detour signs. Stay away from Ripon!
