Gophers and Paved Roads
Do gophers undermining the paved road cause potholes ?
If you mean, do they cause all potholes, certainly not. Potholes
exist in many parts of the country which have no gophers. Water
damage causes most of them, I believe.
If you mean, do they cause some potholes, I doubt it. Paved roads
are built with substantial roadbeds, going down a foot or two, of
crushed rock, which gophers don't seem likely to want to tunnel
