I completed last week my attempt to clinch all of the part of US 160 I hadn't already clinched. My US 160 travels stopped at Ulysses KS, since I'd clinched the route in AZ, NM, and CO, as well as the part in KS west of US 83.
There is a bridge closure detour for US 160 in Dade County MO, which I had to bypass using secondary route O. Missouri 511 says the closure will last a few more months (IIRC, target is early December).
I suggest that you not wait if you can, and plan on coming back later to finish the gap in your coverage of the route. On a route as long as US 160, you're bound to have a closure somewhere. If you wait for a closure to be fixed, a new one will probably pop up somewhere else, and so the entire route may never be open to traffic at any given time.
Traveler services were limited from I-35 (Wellington, which has a Walmart) west to Meade. No danger of running out of gas, but don't be choosy, or wait until your tank is almost empty.
I might have more to add later on other things.
