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

https://tools.geofabrik.de/osmi/?view=routing&lon=-0.85901&lat=42.93516&zoom=14&baselayer=Geofabrik%20Standard&overlays=duplicated_edges%2Cduplicated_edges%2Cduplicated_edges_areas

https://overpass-api.de/achavi/?changeset=158710960

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
