What is criteria for maintenance of egress and exit road of a rural road?

My family and 6 other families live in rural Northampton co. PA. There is 1 road in and out. The 8th family living here bought the property from the previous landowners family when he died. My stepfather and a neighbor used to do maintenance on the dirt road that is the only entrance and exit. My stepfather was issued a certified cease and desist his maintaining of the road and that new landowner will assume maintenance of the road. In the insuing years NOTHING has been done by said new landowner and the families living on the front end end of this driveway because the folks on the back end need to get out. So when it snows WE pay for the plowing and these other folks figure that since we need to get out why should they help with the costs. It is a dirt road. There are pot holes that will swallow your vehicle. The damage being done to our vehicles is a crime. They have no shame and are freeloading off of our shared concern for the welfare of OUR families. I hope I didn't overload. Help
