Hi André Mello,
this changeset has added several errors to the OSM database regarding overlapping and not connected ways:

https://tools.geofabrik.de/osmi/?view=routing&lon=-43.62592&lat=-22.97789&zoom=14&baselayer=Geofabrik%20Standard&overlays=duplicated_edges%2Cduplicated_edges%2Cduplicated_edges_areas%2Cunconnected_open_ends_1

https://overpass-api.de/achavi/?changeset=133996756

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