BUTTE COUNTY, Calif (KTXL) — At least three people were killed when ten vehicles collided on Highway 99 that was shrouded in thick fog early Saturday, authorities said.
The crash involved at least five big rigs and multiple other vehicles, shutting down the stretch of highway in Butte County early Saturday morning.
The crash also sent two people to the hospital with minor to major injuries, the California Highway Patrol said in a statement.
The cause of the crash was under investigation, although low visibility due to heavy fog in the area was a contributing factor, the statement said.
Fog blanketed much of the Sacramento Valley on Saturday morning, reducing visibility to a quarter-mile. Lingering moisture after Friday’s rain allowed for evaporation into low clouds and fog, according to the National Weather Service.
Fire crews in Butte County reported the accident just before 3 a.m. and said Highway 99 will be closed between the towns of Gridley and Biggs for several hours.
No additional information was released on injuries or deaths of those involved.
CHP in Oroville reported just before 4 a.m. that the crash was fatal and happened on the highway just south of Hinamin Drive causing road closures at Biggs East Highway and Spruce.
At 10:30 a.m., Cal Fire crews said Highway 99 remained closed in both directions.
