Feature Line Based Corridor Curb Returns
Shawn Herring of ProSoft walks through the details how to use Feature Lines to design the Curb Return Regions in an Intersection-based Corridor in Civil 3D.

Shawn covers more than the basic mechanics here pretty quickly. Important tips like Feature Line reversal and the Corridor Match Properties command are shown.
If you live and breathe editing Feature Lines you'll like this approach to curb returns.
You can also replace the automatically built Curb Return Regions generated by the Intersection Wizard with Feature Line targets built like this.
Shawn does not do some Region Station matching cleanup in the video. You might want to watch those details in your production work. Overlapping Regions in the Corridor model can produce resolution problems that are hard to find later.
I honestly don't mind the extra detailed work of Curb Return Profile design in intersections, but sometimes the Feature Line solution makes more sense to some.
