The California Department of Transportation plans a $4.5 million project to add and replace curve warnings signs along highways that pass through Shasta County, Siskiyou County and other parts of the North State.
Construction begins Monday, Sept. 15 on Caltrans District 2’s Curve Warning Signs Project. Workers will place new curve warning signs and replace old signs, relocating them if necessary, Caltrans said in an announcement issued Wednesday.
Motorists will encounter one-way traffic control at various locations with up to 5-minute delays between 7 a.m. and 5 p.m. weekdays on highways 32, 36, 44, 70, 89, 139, 147 and 299, according to the announcement.
Caltrans asked drivers to slow down and drive carefully in and around construction areas, follow speed limit reductions and allot extra time for travel delays.
The California Department of Transportation will install new curve warning signs and replace old ones on Shasta and Siskiyou highways starting Monday, Sept. 15, 2025.
