Intersection with multiple assemblies

I have a super-e road assembly as shown that is running into the intersection of a future road stub.  I can not figure out how to get the sidewalk to grade out in the intersection transition I have created for the curb return. Does anyone know a way to get throught this situation? Any ideas would be greatly appreciated. Thanks in advance.

If you're just trying to get the contours looking right then featurelines and grading objects are probably going to be your best choice.  Extract the back of curb line from your corridor.  Draw two more featurelines for the edges of the ramp from the curb up to the corridor sidewalk.  Finish up with a few gradings etc.

Implement a Conditional subassembly into the curb return assembly.
