The California Department of Transportation said northbound I-5 traffic is being screened at Fawndale. "Motorists must have have tire chains in their possession in order to proceed," Caltrans said on its website Wednesday morning. Earlier Wednesday, chains were required on I-5 on all vehicles except those with 4-Wheel drive equipped with snow tires from 3 miles south of Dunmsuir to Weed in Siskiyou County. But the restrictions were lifted by 7:15 a.m. Meanwhile, chains or snow tires are required on Highway 299 west of Burney on Hatchet Mountain in Shasta County, Caltrans said. Chain controls are also in effect on portions of Highway 44 east of Redding.
