A multiple-vehicle crash Thursday morning caused severe traffic on northbound Highway 99.
The crash happened just after 6 a.m. when a pedestrian reportedly darted into traffic lanes and was struck by a vehicle, according to Officer Robert Rodriguez with California Highway Patrol. This incident caused several other vehicles to crash.
There were 10 total injuries, according to CHP. The pedestrian was airlifted to the hospital with major injuries, all others involved suffered minor injuries.
In total, four vehicles were involved.
CHP says drugs and alcohol do not appear to be factors for the drivers involved. It is unclear if it played a factor for the pedestrian.
CHP expected to open the roadway around 7:30 a.m.
By 7:00 a.m., all lanes on northbound SR-99 were closed and traffic was backed up all the way to Olive Drive.
Injuries are unknown and a helicopter airlifted at least one person from the scene.
