Trying to intersect corridors surfaces using intersections

I am trying to find the easiest and simplest way to intersect two corridor surfaces. When I use the intersection feature, I can merge the intersection surface with one or the other profile pretty easily, and if I paste one surface onto the other, one road grade is maintained, but the other is destroyed. Also, even when I force the road grades right with lots of trial and error with breaklines, I cannot get the wider edges of the intersection to get to grade. Is there a better way?

You need to do a google search for help about using the intersection wizard. Your 2 corridors are overlapping, they can't be. You need to introduce multiple baselines and regions so they don't overlap. C3D's wizard makes this relatively easy, but it's a great idea if you learn what's going on under the hood. This is too invloved to show you here. Unless someone is inclined to spend the time.

Thanks for telling me the corridors needed moved back off of the intersection. That hint, combined with this video got it done for me. Anyone who needs to understand corridor intersections, this video is extremely helpful: https://www.youtube.com/watch?v=E-oohJSN3cc
