The short route KY535 is unsigned. GMSV doesn't give much of an idea of when this happened, somewhere between 2008 and 2024. I understand any hesitance to remove unsigned routes in Kentucky, since some minor routes become unsigned and resigned at a whim, and the sheer number of routes is difficult to keep track of. On one hand, this is still on Bell County's route logs, so it has not been decommissioned, and it was signed at some point. On the other hand, it feels almost purposefully unsigned, as there is no evidence of missing signage, no empty posts anywhere, and KY535 is not all that significant, being a 0.6 mile route to Fonde, more a placename than a town. Do as you choose.
