Hi Marco

Think the whole layer/bridge tagging needs reviewing as the pier area is tagged as on layer=1, the road isn't and than the goods_coveyor  (which has no tag to say what type, such as belt), on top of the pier being on layer 1... that would than be layer 2. Maybe the thinking is, if I don't the pier /coveyor disappears in the blue. I never remember.

Unfortunately the duplicate edges are "for-ever" flags by OSMI and over time build up on the daily list, so when it legally can be resolved I'd do so,.. in past I've resorted to making things MPs, the shared edge becoming a single way in 2 MP relations, not really proper. Some mappers make every single shared edge into an MP, to me a maint horror... simple polygons for areas are my thing.
Your list sorted by issue type shows a few dozen, the most poignant those that map highways along edges of pedestrian areas.... highway-highway overlap, not only flagged by OSMI.

FYI if you don't already know it: https://resultmaps.neis-one.org/hdyc-osmi-issues?uid=175882

Anyway, I 'fix' what can be legally fixed and keep the list short making it a 1 minute daily review when the mapping day takes off. Others don't, their choice.

have e nice day.
Rob
