Massive warehouse fire in Slinger, right off I-41

SLINGER, Wis. (WBAY) - Firefighters battled a massive warehouse fire along Interstate 41 in southern Wisconsin.

At 7:29 p.m. on Sunday, May 21, the Slinger Fire Department says it was dispatched to I-41 near Sherman Road. Our sister station reports the building is JFF Wood Products, which sells lumber. Authorities don’t know yet what started the fire.

The fire was big enough that, at one point, officials partially closed the interstate at Highway 60. It’s back open.

DOT cameras show heavy smoke is still crossing the highway Monday morning. Drivers are being asked not to stop or slow down, because that creates an extreme safety hazard.
