So I traced them (and it's just LA125 for that bit) in GMSV, and when I move from 2014 imagery to 2016 imagery, the signs disappear. This isn't "I can't find signs on more recent imagery" but "this sign that I see in 2014 imagery doesn't exist when I move a tiny bit and the image date changes". All LA125/US165 junctions, and where LA124 turns west too. It seems the signs are gone, or meant to be going.
