OR: Missing suffixes

[Nagamasa]

Looks like OR-39 BUS is missing the Bus designation: https://travelmapping.net/hb/showroute.php?units=miles&u=nagamasa&r=or.or039kla

Likewise with OR-223 Spur: https://travelmapping.net/hb/showroute.php?units=miles&u=nagamasa&r=or.or223dal

I'll need to verify with the ODOT GIS what's going on with 39; at some point it went from 39B to the third-leg-mainline of 39.
223 is not signed as a spur. It's a legitimate three-leg route https://maps.app.goo.gl/CqzywA4TXJWRZT4J8

There are only a handful of signed spur routes in Oregon (42S, 86S, and 104S), and as far as I can tell, only 42S is signed in the field.

In GSV, it looks like 104S is shown on every street sign along it as Alt Hwy 101. Yet it wasn't in the original 2007 imagery. Was it actually Alt 101 in those days, but has since been demoted to a mere street name, only used by the Post Office?

Also, I just noticed that ODOT TransGIS shows the nearby end of 101B as being routed up Marlin Ave to the traffic light, instead of to the RIRO across from 104S, and GSV shows BUSINESS 101 signs at that light. So I think that's something that needs fixing in TM. (The other route seemed so illogical that I drove both last time I was there, just to be sure I had clinched it.)

I'm not sure why the Alt Hwy 101 street blades are there, but that's not a factor for 104S or 101B.
101B should be going up Marlin, as that's part of ORH 105 (as is the entirety of 101B). I'll deal with that in a bit.
