Diverging Diamond Interchange

A diverging diamond interchange (DDI), also called a double crossover diamond interchange (DCD), is a type of diamond interchange in which the two directions of traffic on the non-freeway road cross to the opposite side on both sides of the bridge at the freeway. It is unusual in that it requires traffic on the freeway overpass (or underpass) to briefly drive on the opposite side of the road from what is customary for the jurisdiction. (Wikipedia)

Not perfect, but close. Suggestions on improvements are welcome.

From the testing I did with this intersection it handles traffic pretty smoothly. Cars driving on the opposite side is kind of exotic and hence fun to observe ...
