The Angeles National Forest is currently tackling a significant brush fire that started Sunday afternoon, now spreading across more than 800 acres, with mandatory evacuations and road closures impacting the area. The "Bridge Fire," as it's being called, was first reported by the Angeles National Forest officials on their X account at around 2:30 p.m. near Glendora Mountain Road and East Fork Road in the San Gabriel Canyon and has since propelled an extensive firefighting response.

Despite efforts to control the blaze, which now encompasses an 820-acre stretch, all attempts at containment have been unsuccessful thus far according to InciWeb (wildfire.gov), with the fire now 0% contained and continued growth potential looming in the area; meanwhile, high winds and low humidity are contributing factors aiding the spread of the fire, creating challenging conditions for the firefighters. As the fire grew throughout the day Monday, CBS News Los Angeles reported on a series of road closures, including East Fork Road at Highway 39 and parts of Glendora Mountain Road and Glendora Ridge Road, with the California Highway Patrol also shutting down Highway 39 at the canyon's mouth to alleviate congestion.

To safeguard residents, evacuation orders were issued late Sunday for the East Fork communities of Camp Williams and River Community, with those in the danger zone ordered to leave immediately—a clear indication of the immediate threat to life in the affected locales. KTLA noted that the evacuations were mandatory, reflecting the urgency of the situation.

Last seen, firefighting teams were engaged in a fierce battle against the flames from both air and land - water-dropping aircraft were employed to assist the ground crew's overnight efforts, according to officials, despite the fire's continued resistance to containment measures, night-flying helicopters joined the fray to support crews on the ground as they labored through the night. As of this writing, there have been no reported injuries or damaged structures; however, the fire's origin remains under active investigation, while Southern California grapples with not just this blaze, but also the formidable 17,000-acre Line Fire in the nearby San Bernardino Mountains, already responsible for thousands of evacuations, as confirmed by CBS News Los Angeles.
