Make road junctions as overpass in driving scenario app

I am currently trying to design a clover highway with the driving scenario designer app, however when I try to make an over pass the roads just intersect each other. Is there a way that I can create an over pass so that the vehicles do not run into each other at the intersections. Attached is a photo of what I have accomplished so far.

From my understanding you want to avoid vehicles to run into each other. To achieve this you need to overlay the roads properly. To do this you can increase the z value of the rode center. Also you should change the z value of the trajectory.
