See where the grass divider ends, and gets replaced by a jersey barrier for 2 km? That part is the runway - it would require some hours of preparation before it would be usable, it's not quite "declare mayday and dump the plane there."
The thing with the road in Uruguay is that as you're driving, there's basically a yellow sign with a picture of an airplane and an arrow pointing up, and you're like "what the fuck did that mean?" And then suddenly you understand exactly what it meant because you're driving on a fucking runway...
I googled and found a list on https://www.mil-airfields.de/se/list.htm but IIRC there must be something further northwest, not on the list.
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.

And Runway 21 (the same runway in the opposite direction):

and what it looks like when you drive on it: https://www.youtube.com/watch?v=3C5LSrRkFyU
