Hi!
I tried to fix the mapping of circular ways withthe wrong tag highway=mini_roundabout.
Please review my changes:
changeset/62938633
changeset/62938725

Moin! Mir ist der Weg way/617352400
aufgefallen, weil er als highway=mini_roundabout getaggt war. Habe das auf highway=residential geändert. Kenne mich vor Ort nicht aus. Gehört da noch ein junction=roundabout dran? Ein mini_roundabout kann es wegen des Baums nicht sein, siehe auch highway=mini_roundabout

Hi!
I've noticed some ways with highway tag and additional length tag. I think that the length tag makes no sense, the length can be computed by the geometry and wil be wrong when someone splits such a way. Example: way/612840530

Hi and welcome to OSM!
Please watch out for typo highway=trach, I found this on some ways mapped by you during the last hours.

Hi!
Did the Osmose Editor really suggest to use the very unusual tag highway=residential_link for way/264359627 ? I think the old tagging highway=secondary_link was correct.

Hi! Please check typo highway=tp on way/616553275
Not sure if it is a path or track.

Hi! Please check typo highway=yt
on way/622257323
Looks like track, but in this case why not simply add the nodes to way
way/622257297 ?

Hi! Please check typo highway=wood:
way/605318336

Hi!
What is meant with highway=tranmission ?
Maybe you meant man_made=goods_conveyor ?

man_made=goods_conveyor

I fixed a typo here:
changeset/62871286
Hope I got it right?

I did not even see this way, and I did not find any other alternative. Sorry, I forgot to make a foto. There are big tunnels through the new road but they only lead to very narrow ones through the old road, probably meant for small animals.
I asked an engineer working there and he told me to drive back to Gondrexange and drive via Héming.

OK, done

Hi! You changed some link roads here, but according to this table the old tagging was correct:
osm.wiki/Link_roads_between_different_highways_types
What was the reason for the change?

Moin!
Ich habe hier
changeset/62844689
aus dem unüblichen residential_link ein residential gemacht und beide Wege mit den gleichen Tags versehen. OK?

Moin!
Du hast hier mehrere aus meiner Sicht korrekte highway=primary_link nach
residential_link geändert.
Was war der Grund?

Hi! The tag highway=turning_circle should only be used on nodes, not on ways. Besides that it would be a turning_loop.
I've changed way/262267335 back to residential.
See also highway=turning_loop

Hi! Please check accidential (?) highway=traffic_signals on way
way/492247885
It seems to be a highway=residential or unclassified.

Hi!
I've reverted the change to way way/30385229
see changeset/62843327
I assume you wanted to add those tags to a node?

Hi,

I found quite a lot of ways with highway=service:alley
here. The normal tagging would be two tags: highway=service and service=alley
but I think most of them are in fact service=driveway.

Hmm, difficult. I think the question if if there will be a bridge in the future. I did not see anything like that at this place. I found tunnels through the new road near node/3046791465 and near 48.677841, 6.950354, but no further way over the old N4, at least not with a bike.
My current approach would be to change the way to was:highway=path with a note pointing to this discussion.
