A brush fire dubbed the Arrow Fire broke out near the 605 Freeway in Irwindale on Sunday afternoon, sending a thick plume of smoke over the highway and drawing a multi‑agency response. The blaze was reported close to the southbound lanes and near the 2000 block of Buena Vista Street, where crews staged to attack the flames. Firefighters worked the incident from the ground while a helicopter made water drops from above. There were no immediate reports of injuries, and the cause remained under investigation.
What Officials Reported
The Los Angeles County Fire Department said the blaze was reported at about 3:35 p.m. near the southbound lanes and the 2000 block of Buena Vista Street, according to CBS Los Angeles. Aerial footage captured during the response showed a water‑dropping helicopter working above the flames while dozens of county firefighters attacked the fire from the ground. California Highway Patrol incident logs indicated both sides of the 605 were being impacted as crews moved equipment into position.
Holiday Weekend Strain
The Irwindale blaze came during a busy Fourth of July weekend that saw several fireworks‑related fires across the region, stretching local resources and sending extra crews to multiple scenes, The Los Angeles Times reported. That surge has in past years increased the number of small, fast‑moving brush fires that threaten freeway corridors and nearby industrial areas.
History Of 'Arrow' Blazes
The "Arrow Fire" name has been used for larger blazes in the area before, when a 2018 brush fire inside the Santa Fe Dam Recreation Area burned roughly 35 acres and required aerial water drops, according to ABC7 Los Angeles. That history underscores how quickly dry brush along freeway embankments can flare up and force traffic disruptions.
At the time of the latest reports, crews were working to contain hotspots and clear the scene while traffic remained affected in the immediate area. Officials have not released a cause and said they will update the public as investigations and mop‑up continue.
