Emergency crews in Joliet responded on Monday afternoon, April 6, 2026, after receiving reports of a serious single‑vehicle crash on eastbound Interstate 80 at Chicago Street, near the Des Plaines River Bridge.
Illinois State Police confirmed that the crash occurred in an active construction zone, where lane shifts and concrete barriers were in place. The incident happened shortly before 3 p.m., prompting an immediate shutdown of the affected eastbound lanes as first responders worked the scene.
When officers and firefighters arrived, they found a heavily damaged SUV that had struck a concrete construction barrier. The impact caused the driver, later identified as 66‑year‑old Lydia Turner Allen of Joliet, to be ejected from the vehicle. She was the sole occupant, and no other vehicles were involved. The severity of the crash required a coordinated response from Illinois State Police, Joliet police, and the Joliet Fire Department.
Emergency medical personnel transported Allen to Saint Joseph Medical Center, where doctors attempted life‑saving measures. Despite their efforts, she was pronounced deceased at 3:19 p.m., according to the Will County Coroner’s Office. Authorities noted that the force of the collision and the ejection from the vehicle contributed significantly to the fatal outcome.
Investigators determined that Allen lost control of her SUV while traveling through the construction zone on I‑80. The vehicle veered into a concrete barrier positioned along the eastbound lanes near the Des Plaines River Bridge. Police have not yet released information regarding the specific cause of the loss of control, and the investigation remains ongoing as crash reconstruction specialists review roadway conditions and vehicle data.
The Will County Coroner’s Office formally identified Allen the following day, confirming her as the victim of the fatal crash. Officials stated that she suffered multiple injuries consistent with high‑impact collisions and ejection. The coroner’s office is working with Illinois State Police to complete the full investigative report, including toxicology and mechanical assessments of the vehicle.
The crash resulted in extended lane closures on eastbound I‑80 as authorities cleared debris and documented the scene. The incident has renewed concerns about safety in construction zones along the interstate, where shifting lanes and narrow shoulders increase the risk of severe crashes. Community members in Joliet expressed condolences to Allen’s family as news of her passing spread.
