Hi there! I was poking through recent changesets in the Calgary area and stumbled upon this one. It seems you're new to OSM, so first off, welcome.

You've added highway=motorway objects on top of already existing highway=tertiary here. There are two major problems with this.
First, a highway=motorway has a very specific definition, and it is not met here. 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.
Second, you should follow the rule of "One feature, one OSM element": https://wiki.openstreetmap.org/wiki/One_feature,_one_OSM_element
> An OSM element should represent a single on-the-ground feature once and only once.
Here, you've duplicated roads with the highway=motorway and highway=pedestrian.

Speaking of the highway=pedestrian, this tagging has limited application. Almost all use cases should be highway=footway. You can, once again, read the info for each on the wiki: https://wiki.openstreetmap.org/wiki/Tag:highway%3Dfootway and https://wiki.openstreetmap.org/wiki/Tag:highway%3Dfootway
As far as I know the only actual use of highway=pedestrian in Calgary is on Stephen Avenue.
On top of that, as mentioned above, you've duplicated the highway=pedestrian with the highway=footway that was there before. As stated before, you shouldn't be doing that.

I currently don't have the time to revert this changeset but unless someone else gets around to it before me I'll do it at some point later.
