In Search of Roundtrip Route from Charlottesville to Arlington, VA

Hello,

My daughter is about to start UVA and I would like to ride down to visit her from Arlington, VA a few times in the fall and spring. I would greatly appreciate any route suggestions. I would like a route that is as direct, safe, fast, scenic and as free as possible from vehicular traffic. I realize any real route will be a compromise on these route attributes.

Thanks,

Charlie
