When I came into the area where the speed limit changed to 45 , the limit changes up and down several times.If you are north bound it does this. I kept changing my speed up and down according to the sign. When going over the overpass I saw the cop sitting on the left side under a tree . No problem was still going according to the signs, when you get to the bottom of the overpass the limit drops to 45mph. you have to ride your brakes going down because they know you will build up speed without braking all the way down. So if you are over 45 when going down they get you. They told me that I was doing 60 in a 45, wish I had asked to see the radar. There was a SUV ahead of me that was definitely speeding he let him go right thru . I am my mother said I was not doing the speed they said. It you are traveling southbound, you have no overpass to travel over and when you go all the way thru it is 45. They don’t use their little tricks of changing speeds thru southbound but do northbound on Hwy 165. It is a spot on the highway there is no population on that stretch of road, no homes businesses out on the sides of the highway. The town must be off of Hwy 165 to the left .
