The Wibautstraat / S112 going south is crossing the roundabout, and you are not supposed to turn onto or off the roundabout on the north side - there are other ways to get on or off the roundabout.
I first tried a crossing with turn restrictions, and 2 ways crossing without a bridge is often seen as indicative of an error. But I get a node woth a small traffic sign, and I do not see that often on OSM. So I decided for just having the ways cross without an intersection. Is that the right way?
