I was working with a cutomer yesterday on some corridor issues.  When I cam across something that I had really not thought about.  The issue was that the customer’s corridor was superelevated along its entire length, except for a short section at the beginning of the alignment.  When the customer created his intersections using the intersection wizard in Civil 3D, the corresponding section of the corridor had a normal crown. 

My first thought was that we were going to have to update the profile for, in this case, the left edge of pavement to match the calculated profile based on the design cross slope.  But, then I got to thinking about the settings in the intersection wizard and I remembered the Lane Slope Parameters section.  I checked the settings for the Primary Road and the lane slope was set to -2.00% each direction.  I adjusted the left side slope to 2.00% and Voila!  The model acted as the designer had intended.
