Police said a semi was traveling southbound when it entered the construction zone. The driver made a lane change, struck a construction barrier, then over-corrected and struck the median wall that separates northbound and southbound lanes before bursting into flame. The impact shoved the median wall into the northbound lanes, police said.

As a result of that median moving, three passenger vehicles collided with the wall and each other, according to the Racine County Sheriff's Office. As a result of that crash, the driver of a semi traveling northbound made a move to avoid the crash, turned into an eastern ditch lane, went off the road and burst into flame.

Police said both semi drivers died. Of the three passenger vehicles, two drivers sustained serious injuries, including burns and broken bones, and were taken to local hospitals for treatment, police said. The third driver walked away from the crash with no injuries.
