Remember that for state governments, “Highway” is a term of art that does not necessarily mean “elevated controlled access high speed multilane thoroughfare with on and off ramps” but usually more along the lines of, “anything paved, but not dirt.” And the cops parrot this to make themselves sound like they’re very officious and totally not useless doughnut-eaters, and then news outlets follow suit.

For example, my state’s laws consistently use the word “highway” to refer to all paved roads that are under the purview of the state (i.e. not private roads, county roads, or municipal roads), even if they’re not wide enough to have a center stripe. Then what we’d think of as a highway I believe is referred to as a “controlled access freeway.”

Here is the location in question. This is definitely a Stroad, and it is certainly not a freeway. Stroads are well known to be hostile to pedestrians and cyclists. It also appears to have non-separated bike lines, i.e. some asshole just came by and painted bike icons on the existing shoulder, calling it job done.
