As you mentioned, these are the signs that Maryland put up, 11 miles and 7 miles in advanced.

Maryland's paving cycles have lengthened.
For some years you would not often see old worn pavements like the above.
Might this have been a crack-sealing effort in anticipation of a thin overlay or preventive maintenance project?
Kentucky has been doing more pavement preservation projects lately (chip seal, microsurface, slurry seal, cape seal, thin overlay, etc.) on roads of similar quality and utility, and they are usually prefaced by crack sealing.
