The Bridge Fire was a destructive wildfire in the Angeles National Forest, that burned in Southern California's Los Angeles and San Bernardino counties. The fire began on September 8., the fire burned 56030acres and is 99 percent contained.[1] The cause of the fire is under investigation.[2] It is the third-largest wildfire of California's 2024 fire season The fire threatened the area of Jackson Lake, with mandatory evacuation orders in place. As of November 9, the fire has affected at least 100 structures total.

Background

The Bridge Fire burned in an area with little to no recent fire history.[3] Two prior wet winters contributed to the growth of vegetation in the fire area. Weather conditions, including gusty southwest winds and low relative humidity, led to a Red Flag Warning to be issued[4] and allowed for rapid fire growth.[5]

The Bridge Fire is burned simultaneously with the 39232abbr=outNaNabbr=out Line Fire in San Bernardino County and the 23519abbr=outNaNabbr=out Airport Fire in Orange and Riverside Counties.[6] The three concurrent wildfires strained the capacities of Southern California fire agencies, leading them to request additional resources from Northern California and other states.[7] [8]

Progression

The Bridge Fire began at 2:12 p.m. PDT on Sunday, September 8, 2024.[9] [10] The cause of the fire is under investigation.

The Bridge Fire ignited near Cattle Canyon Bridge, for which it was named,[11] in the vicinity of East Fork Road and Glendora Mountain Road in San Gabriel Canyon. It grew to 800acres by early Sunday evening.[12] At 7:15 p.m., an evacuation order was issued for two populated areas in the East Fork San Gabriel River canyon, Camp Williams and River Community.[13] [14]

In the morning on Monday, September 9, the fire had burned 1255acres.[15] At 5:30 p.m. on Monday, September 9, mandatory evacuation orders were issued for Mount Baldy Village, extending between the San Antonio Dam and Mount Baldy Resort. By that night, the fire had burned 2995acres. Firefighters were concentrated on halting any southward progression of the fire, and protecting homes in the East Fork San Gabriel River area.[16]

On Tuesday, September 10, the fire "exploded" to the north and northeast and grew considerably, from about 4000acres to more than 34000acres within hours.[17] It continued to grow overnight, burning an additional 13000acres on its northern and eastern flanks as firefighters prioritized protecting buildings in Wrightwood, Piñon Hills, and Mount Baldy Village.[18] Thousands of people fled those communities, and some reported receiving no evacuation warning before being forced to leave immediately.[19] That day, Luther Snoke, Director of Emergency Services and Chief Executive Officer of San Bernardino County, issued a proclamation of a local emergency in San Bernardino County.[20]

On Wednesday, September 11, 480 firefighting personnel were assigned to the Bridge Fire and California governor Gavin Newsom issued a proclamation of a state of emergency in Los Angeles and San Bernardino Counties.

By September 12, the fire burned 51792acres and was zero percent contained.

Three percent of the fire perimeter was reported as contained on September 14.

On September 15, 2,600 emergency personnel were fighting the fire and had increased containment to nine percent. Cal Fire said that the crews had contained the spread of the fire overnight to be "minimal" at 800 acres. The fire's most active section was in the northwest while the in the east it still affects residents in the Mount Baldy area.[21] Helicopters were unable to fly the prior night due to the smoke hampering visibility.[22]

By September 19, the fire burned 54,795 acres (22,175 ha). Containment reached 49% with progress continuing as two evacuation orders have been downgraded to warnings and one evacuation warning was lifted.[23]

By Thursday, September 26, the fire had burned 54878acres acres and was 97 percent contained.

Effects

Eight firefighters were injured in the course of the fire; according to the Forest Service, none of the injuries were major.

Evacuations and closures

The fire prompted evacuation orders for the communities of Camp Williams, River Community, Wrightwood, and Mount Baldy.[24]

Damage

The Bridge Fire destroyed at least 81 buildings and damaged 19 more: 20 homes were lost in Mount Baldy Village, three homes were lost in Wrightwood, and six cabins burned in the mountain wilderness. The fire also burned the visitor center building at Grassy Hollow. Ski lifts were destroyed at the Mountain High ski resort, but staff there used snowmaking machines to wet nearby vegetation and the resort itself "[appeared] to be mostly unharmed by fire", according to CBS News. Two shacks and equipment belonging to the resort's ski patrol team were destroyed.[25]

The Bridge Fire burned multiple popular hiking trails in the San Gabriel Mountains. 12abbr=outNaNabbr=out of the Pacific Crest Trail between Vincent Gap and Wright Mountain burned, as did portions of the Bridge to Nowhere trail, the Old Mount Baldy Trail, the Bear Canyon Trail, and others.

Political response

The state of California requested a Fire Management Assistance Grant—which allows the federal government to cover a certain percentage of eligible firefighting costs—from the Federal Emergency Management Agency (FEMA) on September 10. FEMA granted the request at 9:18 p.m.[26] Los Angeles County supervisor Lindsey Horvath signed a declaration of a local emergency.

On October 7, the Los Angeles County Board of Supervisors unanimously passed a motion establishing multiple task forces for Economic Recovery, Watershed Hazard Assessment, Health and Social Services, Debris Removal and Rebuild, and Natural and Cultural Resources.[27]
