Traffic was backed up on I-94 South, east of Sibley. Northbound lanes have reopened and all southbound lanes are closed and traffic is being diverted at Dolton.

Police said a preliminary investigation revealed all three vehicles were traveling I-94 southbound at Sibley Boulevard when they became involved in a traffic crash. The crash caused the semi-trailer to strike the concrete bridge support at Sibley Boulevard and then catch fire.

The driver of the semi-trailer died on scene.
