SAN DIEGO -- A building fire spread to brush in Alpine late Monday morning, forcing a freeway closure.
The blaze started as a structure fire around 11 a.m. on Viejas View Lane near Interstate 8, Cal Fire said. Flames spread from a propane tank to the building and then to brush, according to officials.
The blaze grew to about 3 acres before ground and air resources from Cleveland National Forest and Cal Fire were able to stop the fire from spreading any further.
Caltrans shut down all lanes of westbound I-8 at Willow Road due to the brush fire, but they quickly reopened all eastbound lanes. Both westbound lanes remained closed for about an hour. Authorities reopened one westbound lane around 1:30 p.m., but the right lane remained closed while crews put out hot spots.
No evacuations were ordered, according to San Diego County Sheriff's Department.
Last week, the Cleveland National Forest increased their staffing, bringing crews down from Northern California, Idaho and Oregon.
