Yeah, AAA will help you plan that kind of trip.
If not, I know they make software that will plan routes and give distances and "drive time". However, never go by the estimated driving times, they have it taking 70 minutes to get to Omaha (about a 40 minute drive). And never go by "shortest route", they'll have you zig-zagging through dirt roads.
Good luck to whoever's taking that road trip.
