Major Shut Down of HWY 70 Planned After Labor Day

Culvert work in the Feather River Canyon will shut down the entire stretch of the highway following labor day weekend. Following the debris flows slides in June, Caltrans has progressed its restoration efforts to begin installing culverts at Opapee Creek.
The highway will be closed to through traffic between Jarbo Gap (west of Pulga) and the Greenville Wye (junction with State Route 89). If you live in the nearby areas, you will be allowed to drive through the closure area from either side, but you will not be able to cross the location at Opapee Creek.

There is no planned detour for the entirety of the scheduled work, which Caltrans expects to last seven days.

Crews will replace the existing 6-foot diameter culvert with a 10-foot diameter culvert to mitigate future flows from heavy rainfall. Caltrans must close the highway due to the size of the hole for the new culvert leaving no room to have traffic pass through the work zone safely.

On Monday, August 29th Caltrans also begins its drainage improvement project along highway 147 along Lake Almanor. You will see crews replacing culverts at various locations along the stretch from 3.5 miles north of the 89 junctions to about 1.5 miles north of the intersection with County Road A-13.

Give yourself an extra 10 minutes when traveling; there will be various one-way traffic controls through the work area. Work will be during daytime hours Monday through Friday. You can expect construction to end by mid-September.
