The only interesting development from last week’s Transportation Commission meeting was a transfer of jurisdiction. The segment in question is a mile or so of US 65 that was left behind when the interchange in Jasper County was built. You can see it in the center of the above map.
This road has been in its current state for just over a year, but based on the above and its entry in the meeting agenda it doesn’t appear to have been given any secret number in that time.
(BTW, I do have photos of the interchange for a new page. I just haven’t done anything with them yet.)
