Buck, I'm not trying to be nitpicky, but don't you mean I-80 to Youngstown, then I-76 to I-70? This is the Indiana toll road, Ohio Turnpike, and PA Turnpike.

I like the I-80 to I-74 to I-70 to I-79 to I-68 to I-70 route myself - it adds a bit of time but avoids a lot of tolls (and Chicago traffic) and I-68 is a very scenic route.
