Fall drive from PA to Maryland? Why yes there are non- Interstate routes for that.

Yes I have been on the 4 lane section from Marietta OH, to I-79 .... Bridgeport area if my memory is correct without looking at the map.

I drove WV 20 from Quiet Dell to US 460 one time... that is a great ride too.

Thanks for the tip.. I will hafta try all of US 50 / 48 / 33 in WV some day!
Yes the 4 lanes on 50 end at Bridgeport.
I live about 3 miles from Quiet Dell, you can see rt 20 from my house.
