Both the Lawrence Township Police and State Highway patrol sit at this intersection. The State Highway patrol tend to sit on the West side of Route 21 on Butterbridge road off the side of the road a few hundred feet away from Route 21. You cant really see the State Highway Patrol until you cross the intersection if you look that direction. The Lawrence Township Police tend to sit on the East side of Route 21 off the side of the road near the mini car dealership. It is 60mph on Route 21, be very careful especially at night as the Lawrence Township Police will sit there with no lights on.
