How to Model an asymmetric Intersection using DOT's pre-built Civil Cells

I have modeled 4 intersections using DOT's Civil Cells but they were all symmetric.

This last intersection that I am working on is asymmetric and extremely annoying.

The intersection in 2D can be seen here:

 

I am using DOT's pre-build civil Cell which can be seen here:

 

The Prebuild Civil Cell is supposed to look like this: 

It has 2 Curb Tangent Linear Templates and 2 Radi Curb Linear templates. 

What I get is this:

This is the Model in 3D:

 

The left Curb/Radius Template drops to an elevation of 0 and the Surface template can't find the left side EOP. 

The right side of the Intersection I was able to model fine, but the Left side is extremely difficult. I think it's maybe that the Tangent Curb section being cut off on the left hand side?

Has anyone dealt with this type of issue? How should I try to fix the left hand size? If no one has worked on this issue what would be the best way to try to fix this intersection. 

I am able to edit the Linear templates slightly through Project explorer.
