  osgTDS does this for the old-style TIN terrain in VPB.

  I'm working with a client to add grid-deformation functionality to VPB and 
OSG (via a
pseudoloader/saver). You would need a back-end deformation library which can 
calculate new
height values for given points accounting for the road features. I have 
developed this
back-end for my client, but I'm not sure if it can be released publicly in the 
future or not.

  It is very difficult to implement exact feature/TIN trimming with grids. 
You'd basically
need to re-tesselate the GRID into a TIN, and then do something like osgTDS 
does to modify
the TIN. It can be rather expensive to do this on the fly.
