Approaching the Port Mann Bridge entering Surrey on the 1, the speed limit drops to 80km/h. (In the passing lane, traffic is frequently running at 100-110.) RCMP patrol hides in a clearing just on the south side of the bridge behind the bushes and zaps approaching traffic. A good RaDAR detector gives ample warning of the trap, but once you can see the trap with your naked eye, it’s too late if they’ve already nailed ya.
