A brush fire was reported along the Salt River just off Loop 202 in Tempe on Friday morning; it burned roughly two acres and sent crews from six different agencies rushing to the scene. Arizona Department of Transportation cameras captured large flames visible from the freeway as the fire spread along the river.
The Arizona Department of Public Safety provided information about the blaze's location, and Tempe Police and Tempe Fire Medical also responded, according to 12News. Tempe Fire and Medical said fire crews from Tempe, Phoenix, Mesa, Salt River, Scottsdale and AFMA all battled the two-acre fire together. As of the station's report, the cause of the fire remained unknown.
Other Fires Along the River Corridor
This is not the first time flames have chewed through brush along this stretch of river near the freeway. Fire crews battled a similar brush fire near Loop 202 and McClintock Drive in Tempe this past April that generated heavy smoke and snarled freeway traffic, with flames visible on state highway monitoring cameras, as Hoodline reported on the smoke-choked freeway at the time. Back in November 2024, a brush fire along the same Salt River bed near Loop 202 prompted Tempe police to open an arson investigation after witnesses reported seeing a man running from the flames, a case Hoodline also covered.
Other fires have occurred along this stretch of river near the freeway. Tamarisk, also known as salt cedar (University of Arizona Invasive Plants program), is a noxious weed in Arizona and can form pure stands; it can burn hotter than native plants. A July 2025 agency report from the Arizona Game and Fish Department found that non-native northern tamarisk beetles feeding on salt cedar leaves throughout Arizona river corridors leave behind stands of dry, dead branches that act like matchsticks once a fire ignites.
How Six Agencies Converge on One Fire
The rapid, multi-jurisdictional response seen Friday morning is built into how Valley fire departments operate. The Phoenix Regional Automatic Aid System, created in 1979 through an initial agreement between Phoenix, Tempe and Glendale, now serves 29 communities covered by 17 agencies and uses a computer-aided dispatch system, according to the City of Phoenix. Crews from Tempe, Phoenix, Mesa, Scottsdale, Salt River and AFMA responded to the two-acre fire.
Smoke and flames near a major freeway have affected traffic before. During an April fire near Loop 202 and McClintock Drive, smoke slowed freeway traffic, Hoodline has previously reported.
Past Blazes Spurred Restoration Efforts
Major fires along this same river corridor have previously pushed agencies toward long-term fixes. After the 818-acre Cactus Fire scorched the Lower Salt River in 2017, regional partners launched the Lower Salt River Restoration Project to eradicate invasive salt cedar and replant native cottonwood and willow trees, aiming to reduce wildfire hazards and restore the river ecosystem, according to the National Forest Foundation.
No cause has been determined in Friday's fire, and 12News said it plans to update its reporting as more information becomes available.
