How to extend/offset superelevation transitioning slope

Hey RPS Community, I am wondering if anyone knows of an easy way to extend/offset a surface along a corridor using the changing superelevation slope at specified sampling distance of say 10’. See attached. The slope transitions from roughly 2% to 4.5% gradually.
Extending Slopes

In a corridor use an offset slope insteu tion and use Node to Node for the slope beteeen 2 nodes that define the slope that you want to extend to the new edge of pavement

In a surface model if you have two breaklines ise the Offset Slope command in Modeling Toolbox - tbat allows you to create an offset line at the slope feom the ref line based on two lines that define the slope that needs to be extended.
