Finally also heard back from the Saskatoon city government. Its takes:
-- The consistent signage for both SK 11 and TCH 16 on at least the freeway segments of the Circle Drive beltway, including the parts west of downtown included in the HB only in the in-dev cannf system, is not a sign goof, but rather reflects the city's view that all of Circle Drive is part of both route 11 and route 16.
-- Provincial-spec route signage within Circle Drive for routes 5, 7, 11 and 16 (on Idylwild Drive/Freeway through downtown), 14, and a short stub of 219 is not remnant signage from before Circle Drive was completed, but rather is current signage maintained by the city as needed, and reflects the city's view that those routes within Circle Drive are for real.
My tentative proposal, to try to deal with the Saskatoon clusterfork, and clear the way for finalizing and activating cansk:
-- Move the main SK 11 route off Idylwild Dr./Fwy and Circle Drive's southeast quadrant, onto the northeast quadrant concurrent with TCH 16.
-- Add two SK 11 branch routes, one (SK 11 Circle Drive) including the part of Circle Drive not already included in TCH 16. and the other (SK 11 Idylwild) including Idylwild Dr./Fwy within Circle Drive. These branch routes would consist entirely of city-maintained and designated highways. @yakra, this resembles some city-maintained extensions of Alberta provincial highways, which we've included in canab -- your thoughts?
-- Keep TCH 16 as is, including only the northeast quadrant of Circle Dr., and not adding new branches concurrent with SK 11 Circle Drive and SK 11 Idylwild even though the city signs both as TCH 16 as well as SK 11.
-- Leave SK 5, SK 14, and SK 219 as is. Extend SK 7 east to follow SK 14 into downtown Saskatoon (a useless multiplex, but best matches signage on the ground). Each of these routes would include some city-maintained streets, but consist mostly of province-maintained roads outside Saskatoon's maintenance limit.
-- Remove Circle Drive from cannf, since it would now be completely concurrent with cansk (and part with cantch) routes.
I will have more to say about this later, but in the meantime would welcome early reaction.
