Hmm. Tertiary is really for a road that has an official designation, as you
say. The roads I'm talking aren't any different in official status from
their neighbours, but are just more prominent because they are used as
through roads or just "feel" more important.

(I can't really see any visible difference in the page you quoted - except
it doesn't have residential abutters, of course - but is the border just a
tiny bit bolder - very hard to tell?)

Maybe it's generally just obvious from how the roads connect, and I'm
worrying unnecessarily.
