Unless you want to write routines for pre-processing two almost-parallel
ways back into a single way so it can be rendered neatly, I suggest it's a
mapping problem. Don't make work for other people if you don't have to.

Everything about a dual carriageway can (now) be expressed using turn
restriction relations, and it would probably be better if it were done that
way.
