If we had the government make concrete arrows like that today, they would be cracked into rubble in three years because the contractor cut as many corners as they could. (Sorry, My cynical, the past was so much better moment for today)

So they'd be round?

I wonder what semi permanent structures we are building now that future generations will be looking at in 80+ years and wondering about our archaic technology.

The waste water storage tanks at the Fukushima nuclear plant will probably still be around and contaminated 80 years from now. Although I suspect that isn't exactly what you had in mind.

Possibly a lot of traffic structures, since vehicles and transportation may be largely computer-controlled by then, which would re-shape any related infrastructure that has "just made sense" to us in recent history

Is there any plausible reason such arrows would be broken up on purpose? In my mind, I would want more things like this to exist; large physical failsafe markers seem like a great idea.

These arrows, probably not so much, as they are pretty much all in the middle of nowhere. However, general concrete recycling is useful because breaking up existing, unused concrete for works projects tends to be cheaper than, and is more environmentally friendly than, quarrying.

Ah, I did not know that. Thanks!

Earlier quoted context omitted.

I heard it used that way from growing up on Military posts. It just means any fucked up situation. I'm not sure it's known, but I was told it was made popular by troops in Vietnam. The most interesting theory I've seen is that it may derive from fougasse (“land mine”). All of that said, it makes one of the best band names ever.

My understanding is that it is an acronym. Fucked Up, Got Ambushed, Zipped In.

My understanding is that acronym stories like that are almost always apocryphal.

I don't get it. Doesn't concrete crack and break in a messy way? How could it be re-used?
