for something like this, i suggest the model used with the Taconic
Parkway in NY is reasonable. there are sections with a mix of at grade
intersections and full interchanges, and sections w/o the grade level
crossings. so long as the lengths of the sections are reasonably long
(it's a judgement call, but 100 meters is probably way to short) it's
ok to use trunk where at-grade crossings exists or there's no median
or divider, and motorway where motorway requirements are met.

what NE2 did there seems kind of wonky to me.
