On Lost Creek Drive coming from Broad River Rd the speed limit is 45 until you hit a small residential area where it drops to 30. I have seen City of Columbia police hiding in several places in this area. As soon as you are leaving the residential area there is a sharp curve to the left. The speed limit then goes up to 35. But the cops like to sit right at that curve and catch you in the 30mph area. I was recently pulled over for going 42 in what I thought was the 35 zone. He dropped the ticket to 39 in a 30 but also gave me warnings about crossing the center line and because my registration sticker was missing. Watch it in this area!!
