There was a section of road in the center of Japan’s Fukuoka city where a sinkhole appeared out of nowhere. This was almost 100-foot wide and clearly, would have taken at least a month to fix. But the Japanese were able to fix it at such an alarming speed that has left the world astonished. They did it within a week, yes a week’s time the sinkhole was gone and the road was accessible again.
As you can see here, the sinkhole was massive and many sewerage pipelines busted open.
This is the before and after picture of the incident. This was done within a WEEK.
Here is another angle of the sinkhole to show how big it was.
