please review:
the tag highway=closed is rarely used.
Bing shows a normal narrow road.
I guess highway=path, bicycle=yes,foot=yes
matches here?
Please check also way/230965713:
Bing seems to show a barrier=fence around the turning_circle, so bicycle=yes seems to be wrong. Or is Bing out-dated?

please review way/288562048:
I've changed the rarely used tag highway=closed to
highway=dismantled.
Is that correct?

please review way/108166470:
the tag highway=closed is rarely used,
I've changed it to highway=disused.

please review way/79742092:
building=yes
highway=depot
name=WMATA Four Mile Run Garage

it seems to be an amenity=depot now.
Is the name still okay?

please explain what you mean with tag
highway=name_only

please review the roads tagged highway=ice_road or highway=winter_road.
Both are not recommended, see
winter_road=*
and
ice_road=*

okay, erledigt.

please review way/167844207:
the tag highway=ice_road is rarely used,
I think it should be highway=track.
Is it a candidate for ice_road=yes
ice_road=*
or for ford=yes ?
ford=*

please explain:
highway=redeveloped is only used here.
It seems the more often used highway=dismantled matches
as well ?

ja, das Problem haben viele mapper, und jeder findet seine eigene Lösung :-(.
Ich versuche gerade, es wenigstens auf einige wenige Varianten zu reduzieren, damit man die Tags besser per Programm auswerten kann.
In der tagging Liste wurde bescholssen,
dass ein Weg besser kein highway=* tag bekommt, wenn er nicht mal "proposed" verdient hat. Ich ändere daher solche tags zu einem osm.wiki/Tag:note=...

hmm, warum nicht unclassified?
Sieht doch in Bing genau aus wie
way/25556305, und Deine Beschreibung passt wunderbar zu unclassified.

please review: you have deleted waterway=riverbank relations, now
we have untagged ways like
way/238191682

please review way/25556302:
You changed highway=residential to the rarely used highway=route.
I guess that was not intended, so I've reverted this change.

Bitte erklären:
Warum highway=proposed-but-in-limbo-so-please-dont-render-for-now
anstelle von highway=proposed ?

please review way/377534368:
the tags
highway=unclassified;secondary
surface=asphalt;paved
are invalid, the tag
history=Retrieved from v3
should probably be source=Retrieved from v3 ?

please review way/377508298:
the tag highway=unclassified;residential
is invalid.
This problem is likely to happen with iD,so take care or maybe use another editor, e.g. JOSM.

please review, the tag
highway=unclassified;service
is invalid (Ephraim Gully Grove)
This is likely to happen with iD, so take
care ;-)

please review way/24855256:
1) the tag
highway=residential; residential; unclassified; residential; unclassified
is invalid
2) you have combined parts of roads
with different names into something that looks like a roundabout, but it doesn't seem to be one (it doesn't have the "right of way"). Assuming that Bing is up to date,
this looks wrong.

please review:
the tag highway=plantation is only used here, I guess you meant highway=track ?

please review way/377477931:
the tag highway=construction;residential
is invalid, I guess you meant
highway=construction
construction=residential
I've changed it to that.
