New user so bear with me. I have a mainline corridor concept roughed out and a FINISH surface created from it. I would like to force side road (backbone/edges of lane) to match the finished mainline surface elevation inside the intersection, even if that supersedes the SE or normal crown of the side road corridor. The center line profile of side road was already calculated to closely follow the mainline finish grade as it crosses over the intersection so I really just need to control the edges. Seems like it should be very simple - just force the elevation of EOP-LT and EOP-RT to be read from the finish surface of mainline corridor. Do I have to go so far as creating additional alignments and vertical profiles thru the mainline finish dtm? Can this be point control and if so what setting or settings to use? InROADS Suite V8i not GeoPAK.
You will have to create additional alignments for your returns. Please take a look at the video available at the link below. This video provides step-by-step instructions needed for you to complete your design, but it sounds as if you are already familiar with the process.

I didn't watch the video that Sanders posted (though I will, I don't think I've seen this one before), but it sounds like the Multi-Center Curve tool is what you're looking for. This will match up your returns with your mainline corridor edges while also creating the vertical control.
Chuck Lawson posted a video on here a while ago including how to do this. Do a search on here for his name, or "intersection video", or something like that. Maybe someone has the link to it.
