This is something that I've never seen before. Apparently in Missouri most (all?) of their state routes are actually letters instead of numbers. Either a single letter or a double letter but I didn't decode the meaning. I'm not sure what the rationale is, I would think numbers would be easier especially since there might be illiterate people out there driving around. I just thought it was strange.
