MKAD, the 101km circle road around Moscow had almost exclusively this style of intersections up until 2010s, when congestion got absolutely unbearable. Then all of them got rebuilt, typically adding overhead ramps, tunnels, and crazy-long but separate right lines, and by now it's almost impossible to navigate w/o gps navigator (which gets jammed often). Also forget about easily changing direction.

Damn, this is pretty interesting that they had to add the additional bridges.

Does that imply that the merge of two lanes is still too costly?

Also it seems the lane from south east to south west is missing :D it's somehow routed via north first and then goes around the circle.

Yes.

This one https://www.openstreetmap.org/#map=16/55.88495/37.47959 was built from scratch not very long ago. Notice how merges/splits are spread as far as possible.
