Sioux Falls,ND to,La Any advice?

29 south to the 49 to the 44 to the 40 then straight on until morning.

there are backroads trough Nebraska and Kansas that would take 200ish + miles off the trip but I haven’t found a GPS that will route that way yet so a lot of map work.

 

You can run 90w to 25s to 80 w 215s 15s and stay on the freeway 80mph all the way it only adds 50 miles to your trip.
Been there done that Kadoka and Lusk route one to many times.

 

I would take 90 West to exit 129 in Wyoming (Garner Lake Road). Turn left after exiting and travel until you get to Hwy. 50. Turn left. Travel to Hwy. 387. Turn right. Travel to Midwest. Turn left on to Highway 259 (Not sure on this highway number but turn left at the stop sign in Midwest). Take this to I-25 south. Go to Casper, exit 189. I am unsure of these highway numbers but basically make your way down to Rawlins and get on I-80 (check atlas to see the road numbers). From I-80 go west and pick up I-15 south in Salt Lake City. Take this to LA. Best wishes to you!

 

Winner! Winner! Chicken fried steak dinner.

 

There's a setting to change it's priority from shortest time to shortest miles. Not sure if you tried that yet. Mine will find all sorts of obscure back roads for a direct route when I do that.

 

Where the heck are 49, 44 or 40 in Nebraska?

 

They are not, of course. The first paragraph is one route. The second is a rather non-specific other route.
