Is there a good resource for migration pathways in the US?

Question

Most of my ancestors on my mother's side came from NJ to Western PA  to Licking County, Ohio.  Is there any detailed map source(s) of what the routes taken were in the 18th and 19th centuries?

Answer 1

Here's a start on The National Road with a small map, from Family Search.

Answer 2

Travel west in those times was to go to Pittsburg and then down the Ohio river.
