Duplicating highway=path, both with bicycle=designated + foot=designated.

One of them is a part of 2 routes…

I'm afraid I can break routes if I try to fix.

Wegweiser?

highway=turning_circle is on highway=footway — this looks suspicious. Maybe it is not a footway?

highway=living_street became highway=path. Probably, there should be some barrier. Or maybe the living street was finished in another place.

Does this path really has name?
"Panoramaweg" is probably a type.

Adjust position of the sign (guidepost): right now in OSM it is placed on an asphalt road.

Einbahnstraße wird für Radverkehr in Gegenrichtung geöffnet. Bitte dann mit oneway:bicycle=no eintragen.
