5-2-17 investigation continues into interstate 41 oil spill

Authorities continue to investigate a fuel spill on interstate 41 south of Fond du Lac Monday that sent multiple vehicles sliding into the ditch.  Fond du lac County Sheriff’s captain Ryan Waldschmidt says the oil spill occurred in the southbound lanes of 41 from Fond du Lac to near the Dodge County line. Waldschmidt says a few cars slid into the ditch and others pulled off to the side of the interstate. Waldschmidt says the source of the spill is unknown at this time.  “We’re working on that, the state patrol was out there assisting.  But we don’t have any semis disabled or any trucks pulled over, so we don’t know the cause,”  Waldschmidt told WFDL news.  Highway crews spread sand on the interstate and traffic flow was back to normal by about 10am.
