I wish I could remember all the roads I take to avoid DC. You end up on 522 through Berkley Springs going up to 68 then west to Morgantown. I take it every time I go to Stafford VA.
I'd probably stay away from the 95 to 270 route if you think you're going to be even remotely close to rush hour traffic. You can spend hours stuck in 95 traffic.

I just checked, if you mapquest Stafford VA to Berkley Springs WV you'll avoid DC and take about the same route I would leaving my brother's house. It will show a little longer but in reality it takes about the exact same amount of time.
If you're from NE Ohio, take 522 up to the Breezewood tool plaza and run 70 it's faster than 68.

BTW, this route will be much funner than running 95 up to 270. The roads aren't that curvy but they've got some turns.

Sorry to keep editing but I just noticed you're heading to Springfield OH. Take 522 to 68 to Morgantown then 79 up to Washington PA then jump 70 and you're on your way home.
