We have a wonderful road here in Prague. Goes somewhat sharply up hill with a speed limit of 70km/h (43.5mi/h), there's legit nothing along the road and both ends are just junctions. And suddenly, out of nowhere, barely even a bike lane. I presume I don't need to explain that nobody ever bikes here?
Sadly never had the opportunity to take a picture (not like I can just stop there), so here's one from street view, it's hard to see, but there are cyclist markings.
