Hat Creek, CA (January 9, 2026) – A major crash involving a big rig resulted in injuries, traffic closures, and a hazardous materials response Tuesday morning on State Route 89, just south of Eagle Mountain Ln in Shasta County.
The collision occurred around 10:01 a.m. and involved a semi-truck that overturned and came to rest on its side, blocking both directions of the highway. According to the California Highway Patrol, the crash led to a diesel fuel spill and scattered debris across the roadway. The driver of the truck was able to exit the vehicle, and emergency services were dispatched under CHP code 1141, confirming at least one injury at the scene.
The semi was reportedly hauling approximately 38,000 pounds of frozen pizza at the time of the crash. Extensive coordination was required with Cal Fire, Caltrans, and local hazmat units to manage the cleanup and assess the environmental risk posed by the fuel spill.
Traffic control efforts included a full closure of SR-89 near Hat Creek and the use of heavy-duty wreckers for vehicle recovery. Tow companies and Caltrans crews were brought in to support salvage operations and assist with managing the scene.
The highway remained closed for an extended period due to the need for hazmat containment and the removal of the overturned vehicle. CHP is continuing to investigate the cause of the crash, including whether road or weather conditions played a role.
We send our thoughts to those injured in this incident and hope for a swift and safe recovery.
