Hello,
Is "Neighborhood Connector" actually the name of this path?
Happy mapping!

Hello Nzara,
My High German writing skills are unfortunately not very good, so I will answer in English.
Apologies for not waiting long enough for your answer.
I have asked for advice on the OSM World Discord, and the general consensus appears to be that mapping linear highways alongside highway areas (highway=* and area=yes, not area:highway=*) is good practice.
Happy mapping

I've reverted the changesets adding this info.

Due to lack of a response, I have gone ahead and restored the highways.

Bicycles are allowed by default on Oregon motorways. Are you sure this does not apply here?

Hello Nzara,
In this changeset it looks like you deleted a few pedestrian highways in the Friedhofplatz area. I believe these are required for routing purposes and not considered a violation of OSM's "One feature, one OSM element" policy. See osm.wiki/One_feature,_one_OSM_element#:~:text=Object%20oriented%20vs,with%20different%20purposes. for more details.

May I ask why you deleted them?

Happy mapping,

Hello and welcome to OSM!

Is there a sign here prohibiting bicycles? Or any other indication that bicycles are not allowed on any of these motorways?

Happy mapping!

Looks like you made a typo in the operator tag here. I've fixed it :-)

Hello,
Welcome to OSM!
I have done some cleanup in this area. Feel free to reach out with any questions.
Happy mapping!

And added addresses :)

Welcome to OSM! Nice work!
