Even if the parkway shields are mostly illegible, they're still quite an 
improvement over Google Maps (which uses the parkways' unsigned 900x 
route numbers) and Bing and MapQuest (nothing other than the road name 
at higher zoom levels).

Thanks for your attention to detail!

On second thought, some of the Kentucky parkways' abbreviations require 
a little guessing anyways, so maybe the spelled-out images are good 
enough. Someone who tries to navigate based on this map will say "that 
blue and white sign with tiny text", which is exactly how they'll see it 
on guide signs.

I'll get right to it.

By the way, four-digit circle shields appear to have broken over the 
last day or two:
