Line Barrier Costs from External Geometry

I am playing around with Line Barrier - Scaled Costs based on an external set of geometry. I have the base road data with costs in minutes and the barrier I am adding is scenic byways (road that are fun to drive on).
I loaded byway data via 'Load Locations' and use the Geometry as the 'Location Position'. I expected that it would snap to the street data but it doesn't. Therefore because the byway data isn't coincident with the street data the route analysis essentially ignores it.

I am able to select roads from the street data (ones that are on scenic byways) and the load those into the line barriers and get expected results. I can also add a buffer of the byway data and use that as a polygon barrier and get expected results.

Any ideas on the simplest way to do this?

I think buffer is straight forward, and probably most accurately reflects the physical phenomena. It would tag some side roads, but I would expect those roads to be somewhat scenic also. Does the polygon come at a much higher computational cost?

Thanks,
George
