Motorists in the Tri-Valley area are being warned to avoid Highway 84 after a brush fire broke out just off of Niles Canyon Road in rural Alameda County earlier Tuesday.
The fire "is approximately 2-3 acres and contained" as of Tuesday afternoon, according to a tweet from the Fremont Fire Department. As of 2:40 p.m., Niles Canyon Road will remain closed to traffic as mop-up continues; four Fremont fire engines and Water Tender 53 are still on the scene but crews from outside agencies have been released.
"Firefighters are mopping up in very steep terrain—extinguishing hot spots and improving containment lines," officials said.
Fremont, CalFire and Alameda County firefighters responded just before noon on Tuesday to "the scene of a vegetation fire in extremely steep and rocky terrain off of Niles Canyon Rd in #Fremont," according to officials.
Fremont officials said firefighters will patrol the area Tuesday night and all hoses will remain in place until midday Wednesday in case of additional hotspots that need extinguishing.
Bay Area firefighters have also been busy fighting other blazes Tuesday, including a smaller vegetation fire on northbound I-680 near the border of Milpitas and Fremont that has been contained, and a large building fire in San Francisco.
