The cops sit in the driveway of Laffin Chevrolet (on your right if you are coming over the bridge from Sayreville) and ticket people who don’t slow down from the bridge speed (35 MPH) to the unrealistic Main Street South River speed limit of 25 MPH. Be aware that the speed limit changes from 35 MPH to 25 MPH while you are still on the section of the bridge nearest to South River (It’s clearly posted by a speed sign, so if they get you, you won’t beat the rap on the basis of the speed change not being posted.).
