1. Moderation of upslope by two tier benching may be considered.
2. 2-3 meter high retaining wall may be constructed  at the toe of the slope with sufficient number of weep holes.
3. Construction of lined hillside drainage ditches along the road.

Extensive slope cutting for road coupled with saturation of weak overburden material composed of clayey-silt rich soil and highly friable sandstone due to incessant rainfall leds to failure.
