I use Google Maps all the time for route planning. If it tries to put you on interstate highways, you can grab the blue route line and manually drag it over to a nearby non-Interstate route. You may have to do that multiple times, at several places along the route, because it will only use the alternate you select until it finds another chance to put you back on an interstate highway.
Last year, I used Google Maps to plot a route from New Orleans to Lake Dardanelle (Russellville, AR) without driving one single mile of interstate highway. First I let it plot its preferred route, then I dragged the route trace over to nearby US or State highways as often as necessary.
Then I programmed the route into my Garmin GPS by using each highway intersection as a waypoint and letting the GPS connect the dots.
