The road traffic to Nelliyampathy was restricted on Wednesday after a part of the ghat road caved in during the ongoing reconstruction work. The landslip took place between the 14th mile and the iron bridge around mid-day.
Heavy vehicles have been banned while light vehicles were partially restricted. Night traffic has been banned following the landslip.
The rain that lashed different parts of Palakkad, including Nelliyampathy, posed a threat of further landslip. People living in Nelliyampathy raised concerns about being marooned.
Government officials said that tourist flow to Nelliyampathy would be restricted until the road is repaired.
