They run RADAR a lot on the stretch of Route 11 up until it hits Sheetz, and then also you will see them on Route 114 (Walmart, etc). Usually they are before it turns to 55mph though. They are often in the area across from McDonalds, or also I’ve seen them right as you come onto the bridge. Note that if you get a ticket on the bridge, you should probably fight it unless you were the only car on it or the cop was right behind you. This is because that bridge is so long, there is nowhere that the cop could park and get a reliable reading until you are almost off of it.
