Thedford!
If you're headed to Thedford from the south, I would recommend that you buy food, drink, books, fuel, and anything else that you might need in North Platte, since Thedford is, well, rural. If you're staying at the Roadside Inn bring ear plugs, as the Burlington Northern main line is across the street and passing coal trains are almost an hourly event. I don't know where you can buy breakfast in Thedford and the lunch and dinner options aren't all that good either.
I'd expect RT-83 to be clear by the time you get to North Platte.
