There will be more work next week at the site where a rock cliff collapsed state Route 4 last month, the state Department of Transportation announced Friday.
Route 4 between Kelsey Pond Road and Route 22 in Comstock will be reduced to one lane of traffic all week. Traffic will be controlled by alternating signals at both ends of the closure.
The state will be building a temporary access road to the rear of the rock slope that was involved in last month’s rock slide. The access road will be used by DOT and a contractor to remove additional rocks along the slope.
The Oct. 15 slope failure sent 1,000 cubic yards of stone onto Route 4, closing it for three days. Nobody was injured.
Geologists blamed the collapse on blocked drainage channels inside the cliff and recent rains.
