Westbound Highway 40 Expressway near First exit after ile au tourtes bridge
Coming off the ile au tourtes bridge, going westbound, the SQ wait under the first overpass before the exit ramp for Vaudreuil. In fact, highway 40 from there to the Ontario border in the direction of Ottawa, you will see the SQ there at different points almost every day.Definately not worth going past 115kmh. After you come off the bridge till you get to the Ontario border. going over 120 will almost be a guarantee to be stopped for a roadside "chat."
