Caltrans deploys “spyder” rig to remove debris on cliff

Caltrans stopped using explosives and has deployed a "spyder" to move loose rocks and boulders down the cliff.

Meanwhile, near Shamrock Ranch, Caltrans has built a temporary detour next to the southbound lane around the slipout in the northbound lane.

Caltrans says they are monitoring Highway 92 daily for slides and repairing potholes as they are found.  They plan to begin clearing draining channels overnight Sunday, Monday and early Tuesday morning, April 23 through April 25. One-way traffic control will be in effect from 8pm to 4:30am on Highway 92 on those days.
