I have seen Pa State Police running trap on southbound 611 Bypass traffic as you come under the Rt313 overpass. This traffic would be originating from the Plumsteadville direction and not those vehicles entering from Rt313. There is a right hand bend in the road as you approach the Rt 313 overpass. Marked or unmarked car will sit on the grass or just up the edge of the road just as you pass under the overpass. Sometimes the radar car will park in front of a long haul truck sleeping on the edge of the road. Chase cars are located on the on ramp from Rt313 to the 611 Bypass or on the ramp from Broad St to the 611 Bypass.
