please review node/583763607:
the tag highway=trunk
is for ways, what did you try to map?

please review:
is this really a roundabout? Or did you mean
highway=motorway_junction?
See highway=motorway_junction

please review node/1124475394:
barrier=toll_booth
highway=start
The tag highway=start (or highway=end)
is rarely used.
If I got that right, you want to mark the
place where the toll road starts or end.
I think you should better split the corresponding road at this point and
add toll=yes to one part.

please review e.g. node/3402077072:
The tag highway=primary_link is for ways, not for nodes. I guess you meant highway=motorway_junction, so I've changed it to that. See
highway=motorway_junction

please review:
the tag highway=stop_position is
unusual. You used it a few times.
It might mean highway=stop or a
public_transport=stop_position.
I guess the latter.
See http://overpass-turbo.eu/s/cnt
for a list of the nodes

please review node/3809224524:
highway=ele
opening_hours=Mo-Fri
What is meant here?

please review:
I've changed this node to
highway=mini_roundabout
Is it really a roundabout? See
highway=mini_roundabout

thanks for the explanation. Would it be a problem to change the tag highway=genlan:proposed to
something like
highway=proposed
genlan:proposed=yes
?

please review nodes 1912916759 and 1912916760:
highway=statue
note=fixme
Did you mean historic=statue ?

it is also used on node/838047570,
nowhere else in OSM

please review node/830477419:
the tag highway=directions
is rarely used. Is it a traffic_sign=* ?

please review node/27305535:
highway=motorway
name=Tennängsvägen
What is meant here?

@Tom: It was discussed in the tagging list,
I think it would be best to remove the highway tag and add a note for those ways which don't yet have one.

please review way/31611885:
the tag highway=ferry is not needed,
I've remved it.
route=ferry is enough

thanks,I found this tag on 3 other ways as well:
139187674
142656092
142656093

please review:
I've remove the rarely used highway=never_built tag from 6 ways.
They were all also tagged
highway:proposed:historic=*
and maybe should be deleted if they
are no longer planned.

please review way/254250700:
what is meant with the rarely used tag highway=desire?

auch keine Idee? Dann werde ich es in einen Kommentar ändern

Ich habe es mal entsprechend geändert.

please review:
the tag highway=null is rarely used.
The note and the comment seem to say that
highway=construction is matching here.
