Not to pile on here, but I don't think US 50 goes south at Loma. Its been awhile since I did a drive through it using Mapillary (see https://www.mapillary.com/app/?pKey=1491045207904255 ), but I didn't see any US 50 signs.

If you live in the area, I would highly recommend uploading new/fresh imagery so that someone doesn't assume that a malicious actor was messing with the map. I live in Grand Junction, and I don't when I'll be driving through Loma and/or Mack again.

Anyway, just so you know, Mesa County GIS has allowed us to use their (much more) up to date imagery for tracing in OpenStreetMap. You can see it by clicking on the "Background Settings" button in iD (keyboard shortcut "b") and select "Mesa County GIS Valleywide 2022".

JOSM also has access to the 2022 (County wide) and 2020 (Grand Valley) aerial photos with the names starting as "Mesa County GIS".

Thanks for your contributions,

P.S. the local GIS office is having what is known as a "mappy hour" on September 27th. See https://www.mesacounty.us/news/gis/gis-mappy-hour for details.
