Nashville, Tennessee, USA has a ring road that is an odd cross between a
motorway and an ordinary street. Portions of Briley Parkway are a
limited-access motorway, with high speeds and on/off ramps rather than
intersections; other portions are ordinary surface streets, with traffic
lights, and both residential and commercial driveways opening directly into the
Parkway. As you loop around the city, it changes back and forth between the
two forms. To further confuse matters, when it was constructed by joining
together several existing streets, some of the streets kept their original
names and some didn't.

Well it can't be highway=motorway_junction because motorways don't
have level crossings, right?
This image illustrates your question perfectly.
http://alpsroads.net/roads/nj/gsp/n10.jpg Thank you for including it.
If this were a motorway_junction (it isn't) the exit number would be
in the ref tag on the exit node, so go with that.
I would tag the ways as usual, highway="secondary" or whatever is
appropriate here.
highway="traffic_signals"
ref="10B"
If that is indeed a flare for the right turn to 657 Eastbound, I might
mark the first node of the flare with the ref="10B"
