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

https://tools.geofabrik.de/osmi/?view=routing&lon=-6.19978&lat=36.48418&zoom=14&baselayer=Geofabrik%20Standard&opacity=0.50&overlays=duplicated_edges

https://overpass-api.de/achavi/?changeset=163812137

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