A section of the 200 Feet Pallavaram-Thoraipakkam Radial Road near Periya Eri caved in on Saturday due to a rupture in a desalination pipe going underneath the bridge.
Highways department officials said there was a rupture in the pipe underneath the radial road and it was fixed within a few hours.
“This caused only a very minor cave-in. We fixed it in a few hours once we got the news on Saturday,” an official said.
