Hi Ian, have a look at Marianna Road https://www.openstreetmap.org/way/176612937#map=19/-33.69876/151.28378 where I have used islands for stretches in the road that are separated by a concrete barrier. (Height is like a curb so it could be argued if this is segregated enough) but even if the road was split by a proper island for the length of the intersection I would not split the way.
