These are new to me also.

Where it seems there would be a problem is with the traffic crossing over the highway merging in opposite directions. Looking at the orange lanes, the cars coming off NB 85 heading west will all be merging from the 2 left lanes into the two right lanes; simultaneously, westbound traffic on the secondary road wanting to get onto SB 85 will be merging from the right lanes into the left ones. All this over a pretty short stretch of road, about the width of the interstate.

Roads I've seen with this type of cross-merge always feel pretty dangerous to me.
