Cal Fire NEU spokeswoman Mary Eldridge told the Sacramento Bee at 2:15 p.m. that there were several fires located on the side of the freeway near Brighton Street, and they had all been extinguished.
Caltrans officials had closed and then reopened east and westbound traffic on the freeway near McCourtney Road due to the fire, according to a social media post. Officials said the freeway reopened to eastbound traffic in Penn Valley and reopened westbound traffic on a lane near Mill Street for fire clean-up.
The cause of the fire is still under investigation.
As temperatures continue to fluctuate in the west with very little precipitation, the National Weather Service recalled that isolated thunderstorms are possible over the Sierra Nevada this week. Little or no rain is expected, so lightning may cause new fires to start. Sacramento Weather Service Office noted.
