Crews douse 20-acre fire near Mission Trails

A brush fire broke out along SR-52 Friday evening, shutting down three lanes of traffic during rush hour. Today, the fire is at 90 percent containment.

SAN DIEGO — A brush fire that broke out Friday evening along state Route 52 near Mission Trails Regional Park was fully contained midday Saturday, a fire department official said Sunday.

The blaze began spreading on a hillside next to the northern side of the freeway near Mast Boulevard around 4:30 p.m. Friday, according to the San Diego County Fire-Rescue Department.

The spread was halted at an estimated 21 acres by 6 p.m. Friday, and the fire was fully contained by noon Saturday, according to San Diego Fire- Rescue spokeswoman Monica Munoz.

The California Highway Patrol shut down the three-lane westbound state Route 52, while ground and air crews battled the fire Friday. But the closure was lifted as firefighters got the blaze under control that night.

Personnel with Cal Fire and Heartland Fire & Rescue helped San Diego city crews extinguish the flames.

No structures were threatened by the fire.
