Update From the Fond du Lac County Sheriff’s Office:
Traffic flow is back to normal on I-41 and all vehicles that slid off the interstate have been removed. County Highway crews have put down sand to soak up the substance that made roads slick.
TRAFFIC ALERT!!! – A fuel or oil spill on Interstate 41 southbound from Fond du Lac south to the Fond du Lac/Dodge County line has made the interstate extremely slippery. Multiple vehicles are in the ditch and highway crews are en route to work on the issue. If travelling through this area use extreme caution or avoid the area if possible!
