The key causeway across Palar river connecting Madhanur with Gudiyatham near Ambur collapsed in the early hours of Thursday due to rain since last week.
Officials said that this was the second time the causeway collapsed after floods washed away the facility during last monsoon (2021).
Around 12.30 a.m on Thursday, the Collector received an alert on the collapse of a portion of the causeway. Immediately, a team of revenue officials and police rushed to the spot and erected barricades on both sides of the causeway, which is 90 metres long and six metres wide.
