Hi Luisa,
thsiichangeset has created several errors in the OSM database regarding overlapping ways:

https://tools.geofabrik.de/osmi/?view=routing&lon=-67.09582&lat=-17.95209&zoom=13&baselayer=Geofabrik%20Standard&overlays=duplicated_edges%2Cduplicated_edges%2Cduplicated_edges_areas

https://overpass-api.de/achavi/?changeset=132646464

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

You may also like to contact your colleges using the hashtag "#colegiosalesiano" to join your improvement activities.
Kind regards
Guido
