MINNEAPOLIS (WCCO) – Crews were still battling a large industrial fire in North Minneapolis Friday morning that was visible to motorists on nearby Interstate 94.

According to authorities, the fire broke out in a pile of tires and crushed rubber on the 3700 block of North Washington Avenue at about 3 a.m. Friday.

The deputy fire chief told WCCO that the fire was happening at a recycling plant. There were some environmental concerns over runoff spilling into the nearby Mississippi River, the deputy fire chief said.

Firefighters knocked down the bulk of the flames by 6 a.m., but it could still be another few hours before the fire is extinguished completely.

At the height of the fire, flames reached from 100 to 150 feet in the air. The tires contained an amount of oil that crews said was compounding the issues they were having fighting the fire.

The fire was also throwing off a large amount of smoke, but since there was little wind, crews were not concerned that any would drift off into residential areas.

No one was reported to be injured in the fire.

Some reports say there was a fire in this same area on Election Day last week.
