Turning off of Lake Murry Blv. to go to the back of Columbiana Center there is a 30 MPH sign as soon as you turn. This sign is mounted very high and is hard to see. As you progress toward the mall there are no more signs. It is approximatly a half mile to the Columbia city limit sign, the speed limit sign (30 MPH) is about 75 yards past this sign, then it goes to 35 MPH. I was stopped and given a ticket for doing 40. I was told there were several signs on the road. This is not true, and by the time I went back to check, the officer had another car stopped in the same place he stopped me. SPEED TRAP!
