From a disabled datacheck in the siteupdate code (way too many FPs, and kinda "enforces" a certain labeling style) that I'll uncomment every now & again to see what I can see...
These look like they may refer to deleted/decomissioned or unsigned routes.

For those last 2, it's possible it refers to CR365 now if
the point on HI37 is any indication.
While IMO I'm hot so not on slashing a county route number into a state-numbered label, there's precedent for it in IL/MN/MO/WI. Oh yeah -- and NJ (though one could argue that's a slightly different animal, but I digress).
