Superelevation of an EXISTING ROAD

My Project:
I am resurfacing an existing roadway that was originally designed quite a few years ago (and built) with the superelevation opposite of what it should be. Currently, cars are flying off the road and into the fairway of a golf-course! FOUR!!!

My Problem:
I have created an alignment at the Centerline of the R/W. However, I need to maintain the EOP at the low side of the Superelevations. The road consists of 6 major curves which change direction.

My Question:
How can I maintain the desired EOP when it's offset from the Centerline is not a constant? This is crucial as I need to determine where the Roadway grading occurs beyond the existing R/W.

Thanks,
John T.

I think I would attach this as an iterative thing. First I'd use the
existing CL as the proposed profile, and specify the correct superelevation.
Show the existing left and right AND proposed left and right EOP's in the
profile. At the inside of the curves they should match. You'll see
instantly where you need to adjust the proposed CL up or down.
