Hah! I was driving down this route a few years back when I suddenly found myself on an airstrip along with all the other traffic. It was particularly bizarre given that I’d just driven down from tacuarembo to punta del Diablo on largely unpaved roads.
That said, it’s not the first road doubling up as a landing strip I’ve found myself on - there’s a stretch of the main road between Donetsk and Mariupol that was, in soviet times, used as an emergency field for strategic bombers. It’s this relatively quiet provincial highway that suddenly turns ridiculously wide, and goes dead straight and level for what feels like an eternity - 11km looking at google.
Oh, and RAF manston used to have a level crossing across a taxiway.
