The combined affect of high slope angle, loose of toe support due to road cutting, highly deformed lithology resulted in failure along a weak plane (bedding plane) triggered by heavy rainfall.

Though this road section is no more used for commuting between Haflong and Silchar, it is still used by the settlements situated south of Retzawl. Therefore in order to maintain the connectivity, RCC retaining walls and road side drain should be construc

Old HaflongSilchar road
Toe support for the affected slope through construction of strong RCC retaining wall with sufficient weep holes. Construction of road side drain. Widening of the road may be done with easing of the steep slope to reduce the slope angle
Failure along bedding plane. Anthropogenic unplanned construction of road. Reduction of strength on supersaturation due to heavy rainfall.
