I-10 ->
1K or 1I (yes, that's a capital letter I)
2B -> should we 'also' have a 2C here for the other ramp from I-110 to LA-67? Seems two separate graph connections with LA-67 would be justifiable here.
4A ->
44B ->
5A5 ->
5B (yes, signed the same number both directions)
8 ->
8A (yes, I know we have '8A' currently on the ending point, so, if you don't want to make this change I can understand.)
8A ->
8B or 8C (would go with '8B', as that's what's currently mentioned in US-61's file)
==
All changes would also have to be applied to 'LA GRRBat', sans the ending label one @ I-10/I-110.
