The man was transported by ambulance to Advocate Condell Medical Center in Libertyville with critical injuries, Covelli said.

A preliminary investigation shows the pedestrian was walking on or near the roadway.

Based on evidence recovered, traffic crash investigators believe he was struck by a passing white Audi SUV that was traveling southeast on Route 45, Covelli said.
