Hi Edoardo,
this changeset has created errors in the OSM database regarding overlapping ways (blue markers):

https://tools.geofabrik.de/osmi/?view=routing&lon=12.09032&lat=46.40974&zoom=13&baselayer=Geofabrik%20Standard&overlays=duplicated_edges

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
