I've also reverted this changeset for similar reasons as to those in 161918246 and 161918226, but also the fact you've placed a highway=motorway here. 

A highway=motorway has a very specific, very limited definition. You can read the specific definition on the wiki page (https://wiki.openstreetmap.org/wiki/Tag:highway=motorway), however to sum it up, a highway=motorway is a protected-access high speed, non-signalized road. I've been here before and I know this section of Calgary does not meet that definition. The only roads in Calgary that do meet that definition are Deerfoot, Stoney, small parts of 16 Ave, sections of Glenmore, and Crowchild.
