US63:MN30_W -> *90thSt, I'd think. A new TM user might need it in the future. And we need to keep the concurrency with US63.
CR16 -> MN30_W, yes
MN30:CR8_S & CR8_N look good.
US63_N/16 would cause a
NONTERMINAL_UNDERSCORE datacheck error.
US63/16 would be "legal" AFAICS. The manual doesn't say anything about whether or not county routes should be included in
slashed labels or if we should stick to routes that can/could be in the HB or what. I've seen this done in other states. An interesting option I didn't think of, that would avoid breaking .lists.
Existing
US63_N, if you do end up not moving the label to a new location, would be better as an AltLabel. Something like
*90thSt +US63_NWould this also warrant a line in the Updates log?
For MN30, yes. Something like "Removed from 90th St and relocated onto CR 8 and CR 16 between 90th St (labeled CR8_S) and US 63.
For US63, it looks like no in-use labels will be affected, so no update necessary.
