Hi,
Two-lane expressways. I came across one of these when running an
analysis on OSM data in Vermont, USA. I didn't even know they existed.

The one I looked at is tagged as motorway:

That feels right to me. Is it the convention to tag them as highway=motorway?
Reason is I am running an analysis to detect trouble with the main
road network. One trouble flag is highway=motorway without oneway tag,
but that would flag this road here and it's perfectly OK.
Since oneway=yes is the default for motorways (per the wiki, and
apparently some routers), these should be tagged as oneway=no (as these
two in fact are).
It's somewhat more common to have a two-way motorway_link, which should
also be tagged oneway=no.
