Hm. This seems a variation on the
Two separate interchanges numbered 6... next available letter suffix theme, complicated by how the first exit 1 got there first on
Exits 4A & 4B in one interchange grounds.
I can understand not wanting to break .lists & full clinches; that'd likely be a bit rich for my blood too (
1 is in use by 26 travelers). Reminds me of the actual Exit 0s on Interstates that got
fudged to 0A because of
0 being in use at the state line.
I think I-37 went thru some similar funny business with its exits 1 & 1A & pals -- and is now in a state of flux again.
1A doesn't sit quite right, what with 1A & technically being the I-55 interchange.
I suppose I could make the new Exit 1 label "1C", but that doesn't feel right either.
Agreed; doesn't feel right. May be the best of multiple imperfect options though.
Edit: Fixed HB link
