Perhaps proof that J.G. Ballard didn’t really die, he simply took an engineering job at MIT, scientists at that venerable Massachusetts institution have designed a new concrete that will last 16,000 years.
Called ultra-high-density concrete, or UHD, the material has so far proven rather strikingly resistant to deformation on the nano-scale – to what is commonly referred to as “creep.”
This has the (under other circumstances, quite alarming) effect that “a containment vessel for nuclear waste built to last 100 years with today’s concrete could last up to 16,000 years if made with an ultra-high-density (UHD) concrete.” (Emphasis added).
So how long until we start building multistory car parks with this stuff? 16,000 years from now, architecture bloggers camped out for the summer in rented apartments in Houston – the new Rome – get to visit the still-standing remains of abandoned airfields, dead colosseums, and triumphal arches that once held highway flyovers?
16,000 years’ worth of parking lots. 16,000 years’ worth of building foundations. Perhaps this simply means that we’re one step closer to mastering urban fossilization.

Now that's Longnow concrete.
Hasn't the concrete in the Pantheon already lasted for the better part of two millennia? If I wonder if this is a sign that they've figured out how Roman concrete works?
Ancient Roman civilization was carved from stone/granite. And rocks have lasted for somewhat more than 2 millennia.
Anonymous, the Pantheon was made from concrete, which the ancient Romans invented. Look it up.
At last, something reliable to build those markers at the Waste Isolation Pilot Plant out of.
Great, mabye our highways will last more than one freeze thaw season.
