Hi montsec66,
this changeset has created errors regarding overlapping ways (blue markers):
https://tools.geofabrik.de/osmi/?view=routing&lon=1.58755&lat=42.35825&zoom=11&baselayer=Geofabrik%20Standard&overlays=duplicated_edges

https://overpass-api.de/achavi/?changeset=145082562

A you may know, this kind of error irritates routing software and looks ugly on the maps.

Can you please fix this?
Kind regards
Guido
