On this particular bit, since long before Stoney Trail existed (as pavement at least, dunno about on the "books"), I have seen paper maps with "1A" emblems along Crowchild all the way down to Glenmore, and "8" emblems on Glenmore all the way in as far as Macleod (or possibly even as far as Barlow). And of course Macleod is now known as 2A from who-knows-where down to its junction with "Deerfoot" aka 2.erablian wrote:I suspect that the minor highways leading into Calgary lose their numbers at the Stoney Trail interchanges.
IIRC MapArt was one of the ones that showed highway identifiers well inside the city, for what it's worth.
