MT: SR 429?

[mapcat]

This is signed as if it follows Shiloh Rd in Billings. At SR 532, and (with the wrong shield) at Rimrock Rd. Mile markers start at 0 at Rimrock and increase until they die out somewhere north of the zoo. I drove to the end of Shiloh south of I-90 and didn't see any evidence of it at that end.

it's vestige signage.  SR 429 no longer exists - see pg. 6 here - https://www.mdt.mt.gov/other/webdata/external/planning/ALTIS/ALTIS_Road_Log.pdf

Yeah, it doesn't show up here either: https://app.mdt.mt.gov/routeidtool/
