Mostly unmarked cars (blue and green Chargers with tinted windows) sometimes parked. Sometimes rolling. Can clock you in either direction. This is a real money maker for the city of Chesapeake. The road is wide open country four lanes and a large physical median strip. The speed limit is only 55 and 10 mph over will get you a very expensive ticket. And you will get pulled for 10 over. Once into the NC the speed limit goes to 60 and then to 70.
