Firefighters were trying to control a 3-acre wind-driven brush fire Wednesday in Irvine off the southbound lanes of the 241 toll road, authorities said.
The fire at the Portola Parkway exit of the toll road was reported at about 1:10 p.m., said Lynette Round, spokeswoman with the Orange County Fire Authority.
About 75 firefighters responded to the fire, including two helicopters.
“They’re trying to control the fire,” Round said.
Homes in the nearby Portola Springs neighborhood didn't appear to be threatened, authorities said.
“We have not heard of any evacuations out there,” Round said.
