Also the BC routes need to be moved to a cantr system as those are not in the United States.
Breaking up a connected route because there's an international border there seems dumb. Either we tolerate an International Route in a USA system, or the system becomes natr.
The BC routes also seem at first glance to be completely concurrent with canbc routes. To me, including such routes in a tourist route system is a waste of effort, both for whoever is developing the system, and also potential headaches for the maintainers of the concurrent routes. This is different from, say, the Lincoln Highway, which seems to include significant mileage not already in TM.
I understand, and accept this argument (though personally I'm unfussed about a plethora of concurrent routes) - it does make everything harder to maintain. However the route is not entirely concurrent with other routes:
the south side of this route and the
southeast corner of this route are not.
Plus, if we didn't include it, it would be the only multi-state All American Road (well, after I've got the Volcanic Legacy Scenic Byway added to this system this evening) that we didn't include on TM (as far as possible to do so) as a single route. OK, the Beartooth Highway is in as US212, and the Newfound Gap Road Byway as US441, rather than under their names.
Also, the BC routes seem to be deemed part of an international Selkirk route system reaching into Idaho. Those Idaho routes not only are concurrent with Idaho state routes, but I've driven many of those concurrent routes, and never saw any signage indicating they were part of any scenic route system, Selkirk or otherwise. (Ditto the BC routes, though I haven't traveled them as extensively as the Idaho routes.)
You never saw the signs? I found, on Streetview, that these were pretty average in terms of signage - not tons of signs, but only maybe 1 or 2 junctions where it was hard to find signs.
Below are 5 for each of the three jurisdictions (all at different junctions).
