Hello I am Floydian and I will be your waiter on this fine occasion. I've listed my concerns below, which you can chose to respond to individually, or as a group at the bottom. Overall the article is in great shape, and I only have a few issues and suggestions for your attention. Cheers, Floydianτ¢07:06, 15 November 2020 (UTC)[reply]
"By Grainfield, the section that follows old US-40 is the former Golden Belt. A section from Hoxie southward along K-23 follows the former Roosevelt National Highway. Farther north in Hoxie, it crosses the former Kansas White Way and former Blue Line" - The Golden Belt, Kansas White Way and former Blue Line aren't explained or given much context. These three sentences are repeated verbatim in the History section, so perhaps that is the better to place to expand a little on what they are.
"K-23 is not included in the National Highway System,[3] a system of highways important to the nation's defense, economy, and mobility.[4] K-27 does connect to the National Highway System at its junction with US-54 and US-160 in Meade, US-50 and US-400 in Cimarron, I-70 and US-40 by Grainfield, and its northern terminus at US-83 and K-383." - Not sure if K-27 is a typo here. I'd also suggest rewording that sentence, possibly along the lines of "However, it does connect to the National Highway System at..."
"About 3.2 miles (5.1 km) into Gove County it crosses the Smoky Hill River, then Plum Creek about 1.3 miles (2.1 km) later." - Sections should stand somewhat independently. You should specify what "it" is in cases like this.
Do you feel that the Walnut Creek branches or Hackberry Creek are worthy of an article? If not I'd suggest delinking them as with most of the other creeks mentioned in the article.
Take a look at this edit; I changed "In a January 11, 1938 resolution, the overlap with K-4, west of Shields, was moved one mile (1.6 km) north." to "In a January 11, 1938 resolution, the overlap with K-4 west of Shields was moved one mile (1.6 km) north." Your mileage may vary here, but I consider what you had to be a comma splice. I get your use of them: avoiding parenthesis or representing the long stop of conversation. However, "west of shields" is not a dependent clause as it lacks a verb. There are several of these throughout the article that you should fix.
I suggest moving the link to Kansas Department of Transportation from ref #33 to ref #2. Likewise, only ref #1 need link to Rand McNally. I assume ref #18 is intentionally linked to Mr. Clason. This is not part of the GA criteria, but it will come up if you take the article to A/FA (which IMO it would do well at)
