Truncated

It appears that NM 570 was truncated to its junction with NM 567 at the Taos Junction Bridge, with the segment to the east that has not been closed reassigned to CR 110. This is supported by Steve Riner's website and a Google Street View of the areas, but of course the former may not meet WP:RS and gleaning that information from the latter might be WP:OR. Unfortunately, the most recent version of the state's route log (available here) is still the 2010 one, and I cannot find any sort of official document indicating the transfer of control of the eastern segment, although the states own GIS maps refer to it as "Old State Highway 570". I'll continue investigating, but if anyone can find a reliable source, it would be appreciated for the purpose of updating this article. --Kinu ^t/_c 23:46, 11 June 2022 (UTC)[reply]

Northern half of NM570 is permanently closed

While the article is correct that the southern terminus of NM570 is at NM68 at Pilar, the northern terminus is now at Taos Junction Bridge, where NM567 crosses the Rio Grande. Of note, this means that all of NM 570 is currently signed as NM567

The northern half of NM570 was destroyed by a landslide sometime in the 1960s or 1970s (if memory serves, which it very well may not be!). The 0.5 miles of former NM570 immediately north of the junction with NM567 is an unnamed road leading to a trailhead for "The Slide Trail," which is the 1.4 mile position of former NM570 that is entirely closed to vehicles today. The northernmost 4.4 mile portion of former NM570 is now County Road 110

I might get around to updating the page soon, we'll see. I mostly want to find some definitive source that gives the date of the landslide first. If anyone else wants to edit it sooner than I can get to it please go ahead; Good reference material likely includes current and historical USGS topos as well as "The Rio Grande A River Guide to the Geology and Landscapes of Northern New Mexico" by Paul Bauer PhD and possibly the 1994 DeVries and Maurer guidebook to the Rio Grande Anothermedgirl (talk) 18:08, 19 December 2022 (UTC)[reply]
