The trap is north of St. Clair on both sides of the road, to catch northbound and southbound speeders. Southbound, it is just after the bridge that goes over the Cedarvale Ravine tucked beside the Shell gas station. This one is more common, and always has lots of customers (the trap, not the station). Northbound, it is just as you start going downhill on the bridge, they sit in their cruisers and drive after you – the bridge is nice and wide, so they have lots of room to pull you over and take your money. The posted limit is 50 km/h, but 60 would be much more suitable. Consider yourself warned!
