A driver was killed after being struck by a wheel hub that had flown off of a semi truck on Interstate 80 in Joliet on Tuesday afternoon.

The incident occurred near Rowell Avenue. The truck was eastbound at the time, when the wheel hub detached from the rear tractor axle and into opposing lanes, where it went through the windshield of a passenger car and hit the driver.

The driver was hospitalized and pronounced dead shortly afterwards. She has been identified only as a female.

The truck driver, who has also not been identified publicly, has received no charges, and the collision remains under investigation.
