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

https://tools.geofabrik.de/osmi/?view=routing&lon=-100.35153&lat=19.42496&zoom=13&baselayer=Geofabrik%20Standard&overlays=duplicated_edges%2Cduplicated_edges%2Cduplicated_edges_areas

https://overpass-api.de/achavi/?changeset=132721074

As you may know, this kind of errors irritates routing software and looks ugly on the maps. Can you please fix this?
Kind regards
Guido
