Regarding I-81, current 4 is definitely
4A, and current 4A is definitely
4B, though I don't see a way to get the correct labels in place without breaking .list files. Since I-86Bin and NY17Bin only use I-81's number, their 4(81) points could be properly changed to 4A(81) without any adverse effects.
Regarding the Exit 72 and friends situation with NY17Bin and I-86FutBin, current 72B should be
72 and current 72 should be
72B, though again I don't see a way to implement the correct labels without issue.
Regarding NY419, it is signed east-west, but the reference marker order in
NYSDOT GIS support the orientation in the HB, so I guess it could go either way.
Also, NY17Bin (& I-86FutBin) and NY17C are just barely missing a graph connection at Exit 69.
