The goal here is for accuracy, not to imitate another map's style, style
can be handled quite readily by renderers for a specific purpose.

I would also point out that I-93 in Franconia Notch is also two lanes, with

It's not the number of lanes that makes the distinction, but the character
of the road.  People don't expect an undivided motorway, but describing it
as a trunk will cue most renderers to go for something motorway-like but
not quite there.  A super-two with a jersey wall or median strip or some
other physical separation would be a motorway.
