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

1. Removal of slided debris material. 2. Construction of toe support retaining wall with sufficient weep holes along the affected road stretch. 3. Providing lined hill side road drain.
Slope failure occurred on cut slope due to oversaturation of thick slope forming material predominantly composed of highly weathered shale and carbonaceous shale.
