For your corridor to be correct you will need to create both a Bulb Left and Bulb Right assembly.
The baseline will follow around your lip or back of gutter alignment and PGL, the pavement section will need be either BLT or Lane Outside super, such that you can target the centerline alignment, to fill in the pavement section in that region, and the Centerline Profile so that it maintains your desired cross slopes. And All will be well.
Further review suggests that you need only add the pavent sub assembly to the left side of the Right assembly, and on the Left side of the Right assembly. And then in your corridor properties assign the proper targets as outlined above.
Let me know if you want me to create one of those assemblies and post the partial solution for you to follow through and finish the other region. OK?
Although I have 2009 here yours looks to be in 2007 or 2008 version, I do have access to 2008 if required.
