Phoenix Fire Department crews battle warehouse blaze in Maryvale, forcing evacuations and freeway backups

Phoenix Fire Department crews battled a large warehouse fire early Thursday near 19th Avenue and Deer Valley Road in the Maryvale neighborhood of west Phoenix. The blaze prompted evacuations and caused freeway backups as firefighters worked to contain the smoke and flames, officials said.

Firefighters worked to contain the fire and control heavy smoke that spread in the area, officials said. The fire prompted evacuations from the immediate vicinity, although exact numbers were not confirmed by Phoenix Fire Department or other official sources at the time.

Phoenix Fire Department crews responded to the blaze around 6 a.m. Thursday at a commercial warehouse near 19th Avenue and Deer Valley Road in the Maryvale neighborhood of west Phoenix, according to KTAR News.

The large-scale fire required a significant emergency response, with multiple fire units dispatched to the scene, according to Phoenix Fire Department records. While the department did not release details on the number of engines or personnel involved, local news coverage described the blaze as a “massive” warehouse fire. Firefighters focused on preventing the fire from spreading to adjacent structures and businesses in the commercial district.

The incident caused disruptions to traffic in west Phoenix, with reports of freeway backups in the area. However, no official traffic advisories from the Arizona Department of Transportation or Phoenix Police were available to confirm the extent or duration of the traffic impact. The proximity of the fire to major roadways near 19th Avenue and Deer Valley Road likely contributed to congestion during the morning commute, sources familiar with the situation said.

Details on the extent of damage to the warehouse were not immediately available. Neither the Phoenix Fire Department nor local news outlets provided an assessment of structural loss or estimated financial damage. Officials also did not confirm whether the fire was fully contained by midday Thursday or if firefighting efforts were ongoing.

The Maryvale neighborhood is a primarily commercial and industrial area in west Phoenix. Warehouse fires in this part of the city are uncommon but pose significant risks due to the size of the buildings and the potential for hazardous materials stored inside. No reports indicated injuries or fatalities related to the fire, and emergency responders did not disclose any rescue operations at the scene.

This incident follows other recent fire responses in Phoenix but is distinct from a separate structure fire reported in north Phoenix earlier in the week, which affected multiple businesses but was unrelated to the Maryvale warehouse blaze, according to KTAR News.

Authorities have not yet released official statements regarding the cause of the fire or the timeline for reopening evacuated areas and affected roadways. Further updates are expected once investigations and damage assessments are completed by fire officials and city agencies.
