A unique biplanar shear lies at considerable depth below the bridge abutment. The overlying rock is highly jointed and cut by several shears. A landslide occurred in this mass at a down dip exposure of the biplanar shear. Extensive investigation was carried out to delineate the biplanar shear and other significant features in the rock to determine if further slides were probable which would endanger the bridge structure. An analysis was made to determine the extent and nature of treatment that would be required to stabilize the rock mass.
