Oswego, IL (July 29, 2026) – Two people were hurt after a five-vehicle collision shut down Illinois Route 34 for about four and a half hours on Tuesday, July 28, near Orchard Road in Oswego. The roadway was closed in both directions after emergency units arrived shortly after 11:20 a.m., causing significant traffic delays across Kendall County.
A preliminary investigation found that a Chicago man driving a Chrysler Pacifica northbound on Orchard Road may have experienced a medical issue before losing control. His vehicle crossed a grassy median and entered Route 34 east of the intersection, where it struck a westbound semi-truck.
The force of the collision pushed the semi-truck into two other westbound vehicles. Moments later, an eastbound vehicle also struck the Chicago driver’s Pacifica after it had struck the truck.
The driver of the Chrysler and a passenger riding in the semi-truck were taken to the hospital with injuries that were not considered life-threatening.
The cause of the crash remains under review as investigators continue gathering information.
We hope those receiving treatment make a full and speedy recovery.
Why Multi-Vehicle Crashes Can Lead to Long Road Closures
Multi-vehicle crashes frequently require extended road closures because investigators must carefully document how each vehicle became involved. They usually examine tire marks, vehicle positions, roadway conditions, traffic signals, and available camera footage to determine the sequence of events.
Large commercial vehicles can add complexity, as damaged cargo, fuel spills, or disabled equipment may need to be cleared before traffic can resume safely. Crews also work to remove damaged vehicles and inspect the roadway for debris or hazards that could endanger other drivers. Even when injuries are not life-threatening, these steps can take several hours to complete. As a result, motorists are often encouraged to seek alternate routes and expect delays until cleanup and documentation have been finished.
