A similar incident had happened in Anna Salai last year, when a section of the road suddenly caved in near the site of an underground tunnelling for the Metro Rail.

The passengers of a bus evacuated the vehicle after the driver raised an alarm and a car's occupant jumped out after the earth started buckling in then.
