Here's a 2-way motorway sliproad in the UK. It's not the only example


We even have 2-way single-carriageway sections of motorway mainline as well.

Roundabouts I agree with are oneway (actual roundabouts, not just any old 
circular road) - and roads like the Magic Roundabout in Swindon et. al. are 
not single roundabouts.
