Hi PPN_QRGA,
this changeset has created an error in OSM regarding overlapping ways (blue markers):

https://tools.geofabrik.de/osmi/?view=routing&lon=1.86700&lat=44.18340&zoom=13&baselayer=Geofabrik%20Standard&overlays=duplicated_edges

https://overpass-api.de/achavi/?changeset=166614233

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
