Durham PD and NC Highway Patrol will sit under the Highway 70 bridge on southbound I-85 as you round the curve from left to right. You cannot see them until it is too late. This is mostly is the AM rush hour, but have seen them in the afternoons as well. They also sit under the highway 70 bridge on northbound I-85 – you can usually slow down before they hit you with the radar. They also sit on the exit from Highway 70 west to northbound I-85. You cannot see them from I-85 northbound until it is way too late.
