Highway 58, Arizona

In Hillerman's novel The Dark wind, Arizona Highway 58 is mentioned as a connecting route between Winslow, Arizona and the Navajo Reservation to the north. However, the road does not appear on any maps, and there is no indication that it ever did. It is possible that Hillerman got the road numbers mixed up and was in fact referring to either Highway 87 or Road 99, as those are the main routes traveling north from the Winslow area to the Navajo Reservation.
