It's called a Diverging Diamond https://en.wikipedia.org/wiki/Diverging_diamond_interchange

This is kinda like that point where Hong Kong (RHD) traffic meets mainland China traffic (LHD) IIRC. You have to do a little dance to get everyone on the same plan.

Thanks. There's one of these in Santa Fe, NM and I didn't know it had a name. I find driving on it odd but it works.
