I'm un-marking this solved. Or marking it un-solved. Or something.
When I made the update to KY 3303, just out of curiosity I sent an email to KYTC about the removal of the signs. Depending on what they said, I was going to ask if they were planning on doing any other de-signings, or if the route was going to be transferred to the county. I got this reply today, finally:
Dave, I’m not aware of any signing changes on KY 3303. If there is a sign down then it is in the process of being replaced. Thanks,

So this deserves some attention. The route is so short, it's entirely possible all traces of signage could have been removed by vandals or a careless driver. Vespertine, any chance you will be returning to the area in the future (but not too soon) to check whether the signs have been replaced? It won't likely fit into my plans for the rest of this year. Maybe next year, depending on my work schedule.
And to make things even more interesting, I checked with District 6 regarding KY 2405, and got this:
Our traffic support section will review and install route markers for the route to clarify its designation.

That one will be easier for me to check out, but I would appreciate updates from anyone else who may be in the area later this year.
