A four-lane road near the crossing of Hankoujianshe Road and Huangxiaohe Road in Wuhan was seen sinking into the earth on Tuesday evening. The collapsed road spans an area of approximately 300 square meters, NetEase reports.
According to local authorities, the sinking was caused by an underground tunneling machine used for construction of the city metro.
“The sealing system of the shield tunneling machine was damaged that night,” a staff member from the construction site said. “Then an enormous amount of silt and water flooded into the machine, which has caused the ground above to sink.”
