This service road doesn't exist.   Check any satellite view, even back 20 years, no remnant of a road.   I walked this lot extensively from Devon-Mont to AZ 169 two weeks ago, no trace of an old road.   All current Yavapai county records show no easements on this property tax plat 402-132-132, for service road.   This road may have existed before AZ 169 was built in 1971.
