Family members, colleagues, and transportation workers across Illinois are mourning the tragic loss of Calvin L. Holley, a dedicated Illinois Tollway employee who was killed while performing roadway maintenance duties in the early morning hours of Saturday, May 30, 2026.
Holley, 52, of Chicago, died after he and two fellow Illinois Tollway maintenance workers were struck while conducting pothole repair operations on Interstate 294 near milepost 41.5 in Des Plaines. The incident occurred at approximately 4:26 a.m., according to authorities.
The Cook County Medical Examiner confirmed Holley’s identity. Two additional workers injured in the crash were transported to area hospitals for treatment. Their identities have not been publicly released, and officials have not provided updated information regarding their conditions.
According to preliminary reports, the workers were actively engaged in roadway maintenance when the collision occurred. The Illinois State Police are leading the investigation into the circumstances surrounding the crash, and no final determination regarding the cause has yet been announced.
Following the incident, all southbound lanes of Interstate 294 between Dempster Street and Touhy Avenue were closed for several hours while emergency crews responded and investigators processed the scene. The roadway reopened shortly before noon.
Holley served as an equipment operator and laborer for the Illinois Tollway, a position that placed him on the front lines of maintaining one of the busiest transportation systems in the Midwest. In a statement, the Illinois Tollway described him as a respected and valued member of the organization whose work helped ensure the safety of millions of motorists each year.
“Our equipment operator/laborers work on the front line of our roadway system, maintaining safe roadway conditions and assisting motorists,” the agency said. “He was carrying out these duties when he tragically lost his life.”
The loss has deeply impacted coworkers who knew Holley as a dependable colleague committed to public service. Maintenance personnel often work overnight and during early morning hours to minimize disruptions to traffic, frequently placing themselves in dangerous roadside environments to keep roadways safe for the traveling public.
Illinois Governor JB Pritzker also expressed condolences following the tragedy, calling the incident heartbreaking and urging drivers to remain vigilant around roadway workers.
“May his memory be a blessing,” the governor said while encouraging motorists to obey work zone safety laws and remain attentive when approaching maintenance crews and emergency responders.
For those who knew him personally, Calvin Holley was far more than a Tollway employee. He was a son, family member, friend, and colleague whose life extended well beyond the work he performed on Illinois highways. Loved ones remember a man who dedicated himself to his responsibilities and took pride in contributing to the safety and well-being of others.
His death serves as a painful reminder of the risks faced daily by roadway workers across the nation. Transportation employees routinely perform essential duties in active traffic environments, often relying on drivers to follow safety laws designed to protect workers operating only feet away from moving vehicles.
As family members grieve and coworkers struggle with the loss of one of their own, many are also reflecting on the importance of work zone safety and the sacrifices made by transportation workers who help keep roadways safe under challenging conditions.
The investigation into the crash remains ongoing.
Calvin L. Holley will be remembered for his dedication, professionalism, and service to the people of Illinois. His contributions to the Illinois Tollway system and the lives he touched throughout his 52 years will not be forgotten.
