In a mishap, a section of road caved in at an arterial in Chennai’s Anna Salai (Mount Road) near a Metro Rail work site on Friday. However, there was no casualty or damage to property reported in the mishap and authorities have initiated restoration work. Following the incident, vehicular traffic was regulated for a while and some diversions were effected. Another similar incident had happened in the area last year. At that time, a section of the road suddenly caved in near the site of an underground tunnelling for ChennaiMetro Rail. The passengers of a bus had evacuated the vehicle after the driver raised an alarm, and a car’s occupant asked for help.

Thousands of Twitter users had come up with hilarious memes – most of them based on political leaders and actors from Tamil Nadu. An official release from Chennai Metro Rail Limited (CMRL) said that size of the sinkhole was about 5 m wide and about 10 m long and about 2 m deep. “Due to the sudden sink hole formation, the front portion of the bus and car got trapped inside the sink hole,” the CMRL said in a statement. A loose soil pocket along the tunneling alignment, where the boring machine was under operation, was touted to be the cause behind the caving in.
At that time, Chennai metro department had claimed that it has in place a system to monitor the impact of the tunneling work. Further, they had said that monitoring points have been installed throughout the tunnel alignment at intervals of 10 m. Still, such an incident have taken place again in the same are. Further inputs on the news are awaited.
