Steps were taken to repair the barrier wall which was earlier constructed using dry stones. There are 70 hairpin curves in Kolli Hills. According to officials, the works which began on July 12 is expected to be over in a month.

Officials said that the dry stone structure here was constructed between 1956-1961 and RCC technology would work effectively against landslides in the Hills.

The base footing of the structure would have a footing of four metres and it would reduce as it reaches the top layer.
