Unable to answer "How many car lanes does this road have?" for https://osm.org/way/5014365 via StreetComplete 46.1:

The new road layout is almost complete.  It's two lanes on either side, then narrows to one lane in either side, and there are two tram tracks in the middle.  I think the completion date is in a few months.
