HiTBZ1599S,
this changeset has left behind several errors in the OSM database regarding overlapping ways (blue markers):

https://tools.geofabrik.de/osmi/?view=routing&lon=23.81343&lat=40.08839&zoom=14&baselayer=Geofabrik%20Standard&overlays=duplicated_edges%2Cduplicated_edges%2Cduplicated_edges_areas

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
