There is usually a state trooper waiting about 1/2 to 1 mile west of exit 101 on I-20 westbound. That is the Calhoun/Hwy 151 Exit. The trooper is usually parked beside a bridge that is just over the hilltop and you won’t see him until it is too late. The speed limit is 70, and I’ve gone 75 and he doesn’t do anything, but anything higher than that he seems to get. As long as you are going the speed limit or just a little bit over, you should be alright.
