Part of Interstate 5 in Glenn County was closed Thursday afternoon after a tour bus and FedEx truck collided, according to the CHP.
Traffic was being diverted away from I-5 at Highway 32.
The FedEx truck reportedly crossed the center divide and hit the truck, according to Highway Patrol.
CHP Officer Timothy Howath said that at least nine people were killed in the crash. It was unclear how many were hurt.
The section of I-5 that was closed did not have an estimated time of reopening.
“We are aware of the crash in Orland and are cooperating with police during their investigation,” FedEx said in a statement to FOX40.
