Hi,

Saw your revert on revert in the country report and compared how tags on the road mesh with the tags on the parallel path mapped bicycle designated. If use is obligatory I'd do away with a lot and add bicycle=use_sidepath foot=use_sidepath but given the heavy non-conclusive and long discussion on the German community forum I suppose there's no 1 size fits all. I'd certainly test with GraphHopper and OSRM to see how routes come out from north of the 2 bridges to north of the 2 bridges.
