Soon as you pass the Charleroi Exit traveling North on Rt.43, the road opens to a nice straight stretch. Beware, as the road�s grade declines and you start to pick up speed due to the forces defined by Newton�s Law of gravity. The cop sits on the left side at the bottom of the hill shooting his laser back up the hill. His car is hidden by the dirt mound divider that ends as the bridge begins. So you�ll never see it coming, because it looks like you have a clear view of the other hillside going up. I believe that the posted speed limit is 45 mph. but the whole high way has different speed limits assigned by each county. Traveling North from Route 70 seventy until you exit on Route 51 you will encounter speed variations that are between 45 mph. to 65 mph.
