NM: NM159, 181, 195 issues

[vespertine]

NM159: point request for this spot, which seems to be FSR722 or Powerhouse Rd. One of the few places to turn around before Mogollon.

NM181: I think both endpoints are incorrect. On the south end, the route starts are I-25BL, and at the north end, it ends here. At the south end, since NM never cosigns state routes, I'd doubt it runs concurrent with I-25BL, plus there's no signs indicating NM181 along this stretch other than this one, which is probably more an implied TO sign, like NM likes to do. Signage here and here show signs on the north end. NMDOT's milepost viewer shows mileposts that make sense with with this routing.

NM195: This is a mess. So...first off, the dam that NM195 ran on is closed to traffic, with no trespassing signs to boot, making that part unclinchable. No signs at for NM195 at NM177. And from NM179, this sign, indicating NM195 goes only NW from here. If you do so SE, it just leads to a parking lot for a day area. Also, NM195 is still very well signed within the decommissioned part in Elephant Butte, even so that the signs for decommissioned NM171 are entirely gone, but NM195 are still up. So what to do? I would love to see a unified NM195, from NM181 to NM179, even though inside Elephant Butte is decommissioned but still signed. If this is not feasible, at least take NM195Ele and just make it from EleButLim to NM179.

I'll look at these both later, but they seem to make sense at first glance.

One user has clinched the entire route, perhaps before the dam closure.

No signs at for NM195 at NM177. And from NM179, this sign, indicating NM195 goes only NW from here. If you do so SE, it just leads to a parking lot for a day area.

NMDOT's online mapping indicates NM 195 still crosses the dam and ends at NM 177. I'll leave this alone, until NMDOT permanently truncates the route to NM 179 (or the dam). Maybe the dam closure is nonpermanent?

Also, NM195 is still very well signed within the decommissioned part in Elephant Butte, even so that the signs for decommissioned NM171 are entirely gone, but NM195 are still up. So what to do? I would love to see a unified NM195, from NM181 to NM179, even though inside Elephant Butte is decommissioned but still signed.

Unlike California relinquishments, which are usually conditional (such as on preserving continuation signage) so for some purposes the relinquished highway remains in the system, New Mexico's are unconditional, making NM 195 within Elephant Butte completely removed from the state highway system (as NMDOT's online mapping confirms). That makes any NM 195 signage "remnant signage" which I would disregard, even if NMDOT route signage elsewhere in the state weren't so unreliable.

BTW, "Elephant Butte" is kind of a funny name, but being right next to Truth or Consequences helps deflect the snark.

Both changes in my local files, to be pulled in later today. The NM 159 change adds waypoint PowRd. The NM 181 changes truncate the south end to I-25BL, and extend the north end to the barricade north of Alamosa Creek.
