text: A right I read something about un-zorro work done with MapRoulette, now I understand what you mean (I'm a relatively new mapper).
  However I cannot find any Zorro near the place of this Note, when checking with iD.
  Maybe the following changeset has already solved this problem 21st of November 2016.
  http://www.openstreetmap.org/changeset/43852597 
  It mentions "Fix bridge/highway node share", but I don't know if and how to see the situation before this changeset. 
  Maybe a more experienced mapper should look into this, or explain me how to interpret the actual changeset content.
