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

https://tools.geofabrik.de/osmi/?view=routing&lon=-103.36187&lat=20.71849&zoom=14&baselayer=Geofabrik%20Standard&overlays=duplicated_edges

https://overpass-api.de/achavi/?changeset=146226199

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

You may also like to watch out for errors your editor shows you.

Can you please fix this?
Kind regards
Guido
