OK, I'm taking a flying wild guess that this is the one, and if it is then it's about 60 miles East of the Illinois/Indiana line. Between 40 and 60 vehicles. In that nasty weather there could be another accident, so it would still be a help to know "for sure" where the accident you reported is.

It's scary to be out on the road with all the super truckers and 4 wheelers that don't have the common sense to slow down.
That second picture looks more like a junkyard than and interstate highway. Wow, what a mess!
