Hi Giuseppe,
this changeset has created errors regarding overlapping ways:

https://tools.geofabrik.de/osmi/?view=routing&lon=14.29372&lat=37.55530&zoom=14&baselayer=Geofabrik%20Standard&overlays=duplicated_edges%2Cduplicated_edges%2Cduplicated_edges_areas

As you may konow this kind of error irritates routing software an looks ugly on the maps. I have reverted it to fix those issues.

May be you like to educate yourself about how to map cycleways which are part of a road properly:

Kind regards
