The giant sinkhole opened suddenly, swallowing an intersection in Japan, and almost as quickly, it appears to have never happened.
Crews worked around the clock to replace soil, roadbed and utilities within days after a nearly 100-foot-wide by 50-foot-deep sinkhole opened near busy Hakata Station, according to CNN.
Two small holes steadily enlarged Nov. 8 until they swallowed five lanes of traffic.
Workers first had to drain the hole of the wastewater that filled it. After that, crews worked for about 48 hours to replace electric, gas, water, sewer and communication lines and resurface the street.
They added a mixture of sand and cement to fortify the soil beneath it all, completing the project Saturday.
Work on a nearby subway station might have played a role in the sinkhole, officials said.
