Thanks! Though I incorrectly identified Sam Baldock Freeway as having
Highway number 1; it's actually 1C. Whoops. It was 1 before 1W and 1E
were constructed, and 1 being truncated to somewhere around Springfield and
Eugene, with 1C being I 5 north of that after it was built.

The "Standard" renderer still uses the ref=* tag on ways to generate
shields on the main website slippymap, annoyingly, and I've long since
given up on tilting on that windmill on getting carto to work out relations.
What about creating TWO relations for TWO routes? Like, a type=route

Well, in the Oregon case, the "Highway" ref indeed belongs to the way
itself. A route might cross multiple different highways. A route will
frequently traverse multiple different highways (Oregon Route 99E traverses
Highways 1E and 1C, for example, going north to south). A highway might
not even have a route (like state park roads). Even some major highways
don't have routes, though Wikipedia incorrectly identifies Oregon Route 141
as a state route, when it's actually State Highway 141, with no route.
Sometimes, they're ramps, and TIGER was voracious importing these. For
example, http://www.openstreetmap.org/way/70202331 . It's a flyover ramp,
pretty generic in every regard. But it is also State Highway 1WR. That's
Oregon for ya...

YES! Thank you. I have a bone to pick about lane tagging as it relates to
bicycle lanes specifically on this front as well. How are HOV, bus and
taxi lanes counted but bicycle lanes not? Zero sense... Unlike the ref
issue which is relatively major, I switched a couple years ago to including
bicycle lanes in lanes=* and lanes:forward=* and lanes:backward=* and just
added the appropriate lane access tags as necessary, as is done with HOV,
bus and taxi lanes the world over. One complex example of that would be
http://www.openstreetmap.org/way/361641534 , though turn:lanes is kind of
hamfisted there; a more accurate turn lane tagging would be...
Ground truth makes no logical sense sometimes, and OSM's unrelenting logic
struggles with these cases sometimes.
