Hi  tabacus,
your recent changesets have created several errors in OSM regarding overlapping ways (blue markers):

https://tools.geofabrik.de/osmi/?view=routing&lon=13.95970&lat=41.97428&zoom=14&baselayer=Geofabrik%20Standard&overlays=duplicated_edges

https://overpass-api.de/achavi/?changeset=166699398

As you may know, this kind of error irritates routing software and looks ugly on the maps. Can you please fix this?
Kind regards
Guido
