The fire broke out just before 12:30 p.m. Friday after a pickup truck driving northbound suffered a broken drive line.
The broken parts sparked a fire in the center divide of Highway 101 before spreading to either side of the highway.
No structures were damaged. CAL FIRE says firefighters were able to protect 20 homes that were initially threatened by the flames.
Evacuation orders were issued for people living on Santa Margarita Rd. and Powerline Rd. Those orders were lifted several hours after the fire broke out.
Highway 101 saw heavy traffic throughout the afternoon, but all lanes of the highway were reopened later Friday.
