Spot Where Road Collapse Accident Occurred
The road surface looks new here. In 2020 October, a hole opened in front of the entrance of the garage shown in this photo. The accident happened a few days after a shield machine constructing a tunnel for Gaikan Expressway under this spot. Since the tunnel is more than forty meters deep, it was thought that there would be no impact on the ground surface. But investigations revealed that the work made some voids in the ground.
In 2023 January, work began to demolish about 40 houses and repair the ground. It will take about two years.
