Hi

I wish to create a new road crown. please see snip below. the road crown has deteriorate and the contours spike down to a lower level after the solid white lines. how to i project a new accurate road crown to complete my inlay design

Well - the bent contour shows a TIN face edge isnt as it should be. 

Two items - turn TIN faces on for your corridor surface.  Review the breaklines contents of the corridor.  I assume the solid white lines aren't part of the surface.
