On highway #2 just east (uphill) of the arched overhead CP train bridge (this bridge is known locally as " The Hole in the Wall ")

Durham region police face their radar mainly uphill, catching those coming out of an 80 into a 60 kph zone going down a huge hill. They, however, have been known to face their radar downhill toward the arched opening. Drivers going uphill through the opening (speeding up to get up the hill) can’t see the trap because the arch is very narrow and at the bottom of the hill.
