Car Plunges Into Chennai Sinkhole Near Tidel Park
A road near Tidel Park in Chennai suddenly collapsed as a car drove over it.
The car fell into a deep hole and turned upside down.
A man and a woman were inside, but both got out safely.
Workers began removing the car and fixing the road.
The collapse also caused traffic delays.
Officials said an old sewage pipe under the road may have failed at a joint, washing away soil beneath the road.
Chennai Metro Rail Limited had not said whether Metro construction contributed to the collapse.
A similar road collapse nearby in 2025 injured five people.
A car carrying a man and a woman fell into a sinkhole near Tidel Park on Chennai’s Old Mahabalipuram Road on Thursday morning, October 8, 2026; both occupants escaped unhurt.
The road collapsed while the car was passing, and the vehicle overturned in a crater estimated at about 10 feet deep.
The collapse disrupted traffic; workers began removing the car and repairing the damaged road.
Officials attributed the collapse to a failed joint in an ageing sewage line beneath the road, while Chennai Metro Rail Limited had not clarified whether Metro construction played a role.
A similar cave-in near Thiruvanmiyur Junction in May 2025 reportedly followed a sewage-pipeline failure and injured five people.
