Description:

Pros:
-100% free-flowing
-Weaving and conflict points have been eliminated
-Traffic on the main carriageways travel in a straight path and no longer need to crossover

Cons:
-Very expensive to build due to grade separation
-Requires a lot of land

The second design in my DCMI series, it had occurred to me along this civil engineering journey that when the main carriageways on a DDI (aka Double Crossover) become grade-separated, it is no longer necessary for them to crossover at all! That is what this design investigated as a proof of concept.

Eventually, I realized this interchange does not have an intuitive and obvious title!
It diverges like a DDI but is grade-separated.
It is grade-separated but doesn’t crossover like a DCMI.
It has left-turning off-ramps that sweep outwards like a windmill interchange.
But it is 3-levels, (more than windmill or diverging windmill interchanges).

Above all, it is a SERVICE interchange because ultimately, it interchanges traffic between a freeway and street.

So I dub thee the Hybrid 3-Level Service Interchange!

Despite extensive testing, glitches occurred during the saving process in the Asset Editor. Sometimes sunken road segments which were formatted to follow via "ground" in Road Anarchy appeared covered by earth and had to be reformatted / upgraded.

Also, not all of my lane directional arrow / lane linking configurations survived through the upload process which is why I set Traffic Manager as a requirement. Honestly, if you are advanced enough in your road design to mess with DCMI’s and other advanced interchanges, then you should already have that mod anyway.
