https://github.com/TravelMapping/HighwayData/pull/3182I took care of M-26 and found a couple other adjustments to make (repositioning and renaming a point shared with US 41 and deleting a few unnecessary shaping points). Interesting that you didn't point out the US41_S & _N labels mixed in with the others, which I'm keeping for now.
As for M-94, there are a few other deserving visible points worth adding too. But the western part needs some point-drift-related TLC that I'm unable to provide for now, so I'll put all of this off until I have time to do a full system review. Ohio's comes first so there's no timetable for this yet.
