Wide Roundabout highway exit (without quay walls)
The wide Roundabout intersection is commonly used (e.g. in the UK), where an ordinary diamond intersection cannot cope with the capacity.
Versatile, efficient, small, simple, and cheap.
Version with the sunken main 3-lane highway which crossing with a 4-lane avenue. Of course, you can easily upgrade the roundabout to more-lines-highway. Same with avenue.
