Last week, there was a giant hole in the middle of a Fukuoka, Japan street, spanning 98 feet long by 88 feet wide by 50 feet deep, due to underground subway work causing a sinkhole.  Less than 7 days later, all the utility lines were repaired, the hole was filled, the asphalt laid, and the road is back open.  It was a true testament to what a considerable amount of manpower and money can do in a short period of time.
