Hello! fyi: the tagging sidewalk=no is only for streets, where there are no sidewalks at all. Here are regular sidewalks, in this case separately mapped, so sidewalk=separate (or sidewalk:both=separate) is correct. Some sections have been changed already by other users, the remaining I've changed now. More information you can find on the wiki https://wiki.openstreetmap.org/wiki/Key:sidewalk?uselang=en#Values
