The rock slide occurred due to intersection of joints and the exposed rock beds dip and slope towards valley side. The weathered rock material is unstable along the extensive slope cut.

1. Construction of toe support retaining wall with sufficient weep holes. 2. Removal of slided material on the road side. 3. Trimming of crown scar along its length. 4. Removal of loose rock blocks precariously occurring at crown portion.
1. Toe cutting of slope during road construction and road widening, 2. Slope forming material predominantly comprised of highly weathered intercalation of shale-siltstone, which is dipping towards valley side leading to slope failure.
