M1 in Queensland is the only other route that has more than one exit series; while I left the Bruce Motorway numbers without a (x) suffix, I put all the Pacific Motorway in (P) suffix.
Was actually the subject of the next batch of commentary I had started working on, but had paused because I've been entangled in other things the past few weeks. Might as well share this now:
AUS-QLD M1:- 84(P), 85(P), and 85A(P) can be combined into two points or maybe even one
- combine 71(P) and 71A(P), one point per interchange
- combine 28(P) and 28A(P), recenter over Grandis St overpass
- the (G) and (B) suffixes can be removed - there is only actually one set of exit numbers between these two, and it's clearly the longer and thus more "main" section compared to the (P) numbers.
- also opening the question on what the remaining suffix should be. Precedent from I-87 in NY suggests (PM) might be more appropriate than (P). Precedent from zafn suggests (S) for South.
- combine 112(G) and 112A(G), one point per interchange
- 122(G) -> *122. The access point here closed a few years ago.
- 138(B) needs recentering
