text: Incomplete separately mapped sidewalks in this area are making pedestrian routing impossible.  If they're going to be mapped this way they need to connect to each other, and the roads, at every single intersection, and should all be tagged as footway=sidewalk/crossing, and can't have any gaps or missing segments where gaps don't exist in reality.
  
  An alternative might be to remove the highway=footway tags and add sidewalk=both/left/right/no to the roads instead.
