I guess Mapcat (at least) saw the same sign tree, @ OH 53 & US 224, outside of Tiffin, that I did...
(For what it's worth, Dave, I didn't see any other mention of a Truck OH 231, or Truck OH 100 (besides the one right next to the RR overpass) in Tiffin during my visit last month)
That said, I know Mapcat already added the truck routes to Ohio's state route collection, however, the mileage doesn't seem to be added to the collection. The total miles for Ohio are still at 19,421.3 and it should be at 19,430.23. (my personal miles traveled, in Ohio, went to 9955 on July 2nd, and didn't increase with the new routes added on July 4th)
Not sure what technical glitch occurred, but IMO, should be investigated.
