I don't think there's been a real effort to tag these yet, the four in
Oregon I'm aware of are the Lewis & Clark Trail, Oregon Trail,
California (aka Applegate) Trail and the Oregon Outback Route.  Each
of the first three seem to use their own trailblazers and may be
interstate in scope.  The latter and newer routes use extremely large
trailblazers.  http://www.examiner.com/images/blog/wysiwyg/image/Oregon-Outback-Sign.jpg

Kansas Turnpike (there's only one) uses the KTA shield universally,
often in conjunction with, but usually in absence of, I 35 signage.
Oklahoma (like Kansas) has a toll and non-toll highway network, and
they don't overlap (with the exception of I 44, which is dual signed
with the Turner Turnpike and Rogers Turnpike; guide signs leaving the
Turner Turnpike instruct drivers to "take I 44 to the Rogers Turnpike
to Joplin" more or less treating I 44 as nonexistent on the turnpike
lengths, despite being dual signed!).

All of Oklahoma's turnpikes use identical trailblazers, the only part
that changes is the name on the top half of the roundel (in this case,
"Indian Nations").

FM and RM should render identically (obviously since they're actually
the same network), LOOP, SPUR, NASA, Texas I all recognize.  I don't
see TOLL or REC, and no idea what PR is...  Cool on handling such a
complex network well.

I would be inclined to do the same (despite the nonstandard reference
before network signs that that route uses).
