Thick black smoke poured above Interstate 15 near Midvale’s Main Street on Thursday as firefighters rushed to a working blaze in the city’s western corridor. Drivers on the freeway reported seeing a towering plume, while nearby residents said they could smell smoke as crews moved in. At the time of the initial reports, officials had not yet released any information on possible injuries or what sparked the fire.

What we know so far

According to ABC4, the Unified Police Department confirmed there was an active fire near 700 West Main Street and said a public information officer was headed to the scene. Early coverage noted that the cause of the blaze was still unknown, and it was not yet clear how many fire units had responded. Photos credited to Meg Monsivais and to UDOT showed a dense column of smoke rising over the southbound lanes of I-15.

Where this is happening

Midvale sits along the Wasatch Front and is split by I-15, which means any plume of smoke over the freeway is hard for commuters to miss, according to Midvale’s city profile. The city leans on regionwide public-safety partners such as the Unified Police Department and the Unified Fire Authority to handle major incidents across the valley. That setup often brings multiple agencies to larger calls in Midvale.

Traffic and safety

ABC4 reported that vehicles and traffic cameras captured “black smoke” hanging over I-15 and said the station had reached out to officials for more details. Drivers in the area described slowdowns and reduced visibility while crews worked the scene. Hoodline will update this story when public-safety agencies release additional information.
