Hi FlySkyline! Why did you choose "surface"="concrete:lanes" for these sidewalks? Based on the wiki (https://wiki.openstreetmap.org/wiki/Tag:surface%3Dconcrete:lanes), I think you may have wanted just "surface"="concrete". 

There seem to be quite a few sidewalks around Winnipeg that are tagged like this. I just picked this particular changeset arbitrarily.
