The Hyundai SUV plunged into a large sinkhole on Chennai’s Old Mahabalipuram Road, also known as OMR, early in the morning on Thursday as road safety in one of the city’s busy IT corridors was questioned. It fell directly into a roughly 10-foot-deep section of road that suddenly gave way near Tidel Park, where underground metro construction is ongoing on the ground.
The incident occurred in the early morning when OMR was running in regular traffic. Videos shown on the scene showed the Hyundai SUV tilted sharply inside the large cavity, with part of the vehicle hovering above the road surface. The sudden cave-in placed the occupants and other drivers in the area at risk.
According to the information available, a man and woman were in the car when it fell into the sinkhole. Both occupants escaped without injury, and bystanders and police personnel rushed to help them immediately. The absence of serious injuries was a relief but the incident has raised new questions about the condition of roads in areas where major underground infrastructure work is taking place.
Hyundai SUV Gets Trapped In 10-Foot Sinkhole
The vehicle plunged into the road after part of the surface collapsed, the investigation revealed. The depth of the cavity was estimated to be around 10 feet, leaving the SUV at a sharp angle and highlighting the extent of the road damage.
Videos circulating from the site showed people gathering around the vehicle to try to help the occupants. Police and members of the public helped get out safely.
The incident also underscored the risks of sudden road collapses on heavily traveled urban routes. A road surface might be ordinary to drivers and some underground soil or construction activity may weaken the road surface. Drivers may not have time to react when a part of it suddenly gives way.
Incident Occurs Near Ongoing Metro Construction
The sinkhole has already emerged along a stretch of underground metro construction. The presence of large infrastructure work has added to the attention and the reason behind the collapse has yet to be determined.
But authorities will look at the road and the underground structure to understand what caused the cave-in. Construction activities, changes in soil conditions, water movements, or weaknesses on the road could be factors to be investigated.
Relatively early repair work has been initiated at the site of the damaged road as officials try to make the road safe for traffic. It could also lead to additional inspections of nearby OMR areas where construction is ongoing.
Second Such Incident Raises Road Safety Concerns
The latest incident is especially concerning because it is the second road cave-in in the area in a short period. Repeated incidents can raise concerns among motorists who depend on OMR every day for commuting between residential neighborhoods, offices, and other parts of Chennai.
Old Mahabalipuram Road is an important transportation route because of the large number of technology companies, office complexes, and residential developments along the corridor. Tidel Park and other large commercial areas attract thousands of employees and commuters, making road safety an important concern.
Such a sudden sinkhole on a busy road will have a negative impact beyond the vehicle involved. A car may not see a new cavity from other drivers in heavy traffic or in poor lighting. A damaged road can make them diverge, and the traffic is more congested in the road as repair crews work on it.
Authorities Probe Cause Of Chennai OMR Cave-In
The cause of the Chennai OMR sinkhole remains to be determined. The collapse was linked to underground construction or the road surface collapsed, officials said.
Such an investigation is needed because knowing the actual cause would help prevent similar incidents in neighboring areas. If construction activities were found to have contributed to the problem, authorities might need to examine whether additional safety precautions, monitoring, or structural assessments were needed in the work zone as well.
The road agencies and construction authorities may also have to assess whether underground work has affected soil stability beneath neighboring parts of the road, and if so, how much underground work has affected soil stability for adjacent parts of the road in the same way so far. This could help to identify those vulnerable areas in case one section collapses to another section of the road.
OMR Commuters Face Fresh Safety Concerns
The incident has once again highlighted the challenges of carrying out large infrastructure projects on busy city roads. The long-term benefits of metro construction are great for public transport, but during the construction phase, traffic, road surfaces, and underground utilities are also key.
Imagine the traffic today on OMR 😭. Luckily decided to take WFH today 🫣 https://t.co/uBuoxGFWkt

Commuter safety in the situation is the immediate priority: Making sure that affected sections are properly barricaded, repaired, and inspected before traffic moves in the direction of normal traffic is the first priority for commuters, and it is at the same time important to have those sections of road blocked and to be repaired properly; they can be done before the road can go back to normal traffic.
The two occupants had managed to escape without serious loss of life at the time; the drama of the incident did not result in any loss of life, but it has brought attention to the problem of roads under construction work.
The problem will be assessed, and further safety measures would need to be put in place as repairs continue and investigations into the cause of the collapse and how dangerous the road remains to be done in the vicinity to ensure there are more safety precautions in place. Drivers using OMR must be cautious around construction areas and recently rebuilt sections of road for road safety.
As OMR remains one of Chennai’s main IT and commercial corridors, the safety and stability of the road will continue to be very important as underground metro construction is developed. The findings of the investigation could help to determine if any future actions are needed to avoid sinkhole events.
