In my area the US routes are mostly but not all using three relation scheme as are a few California state routes. At least for my editing style using JOSM, I much prefer the super/sub relation scheme as I find it easier to fix things when broken.

I can say this is also largely the case in Oklahoma, though for routes
with only one relation, then it's because splitting it is gross
overkill because the end of the route is on a single carriageway on
both ends and is thus extremely easy to validate with pretty much
everything except id anyway.
