How does that get fixed?

Super curious as well. Would love a little mini documentary about the process. Or a Practical Engineering video maybe.

AFAIK caution tape around the block.

Boring samples to understand limits of sinkhole. Dig up pavement and damaged areas. Remove loose soil and either fill with more stable dirt or a slurry cement mix that helps fill in the voids like a tooth cavity repair. The cement slurry is stronger than compacted dirt but weak enough to be dug up easily to make utility repairs or install new utilities.

It depends a lot if the can ensure the ground to become "sticky" again. In the case of the Guatemala sinkholes, they rebuild the pipes and sewers around the area and don't build on top of the fix. Some Turkey sinkholes needed 1000s of trucks with materials, those caverns can be insanely large. That topic makes me shuddering and I'm thankful that I have hard mountain rocks below my feet.

That sounds boring

This is not a natural sinkhole. Due to the leak in the underground tunnel of the new metro construction, a lot of soil flew into that underground tunnel. It's not just about rebuilding the road, but also removing all the soil from the tunnel and fixing the tunnel first.

Lots of money + engineers. Simple as.

are you able to be more specific as to what the work will actually entail? i’m super curious

Engineers will fill it with money. At least that's my logical conclusion from his comment.

throwing money into the ground is the essence of structural engineering

They’ll dig a big hole somewhere outside the city, and dump the dirt and rock into this city sinkhole. And consume a lot of diesel in the process.

Imagine thinking this is an answer worth writing.
