I can confirm that the Mountain Parkway Expansion logo sign is just that; a promotional/marketing thing.
There are three old-style Mountain Parkway signs remaining in the wild of which I am aware. All three are located in towns at busy intersections that would make acquisition by means of questionable legality a bit difficult.
I have a second-generation (logo in the square instead of the cutout circle), uninstalled, Daniel Boone Parkway sign in my office.
I would kill to get my hands on the old Mountain Parkway shield, with the Hal Rogers banner.
I think you mean Bert T. Combs.
As for the bill itself, I haven't seen it, but it would require another wasteful massive resigning such was done when the signage was changed to the current format. I understand that was done in an attempt to proliferate the "Kentucky Unbridled Spirit" logo, but as big of a supporter as I was of Gov. Fletcher and his administration and his Transportation Cabinet leadership, I think this was a mistake.
