A semi carrying fireworks rolled over and caught fire, blocking northbound lanes of Tri-State Tollway for several hours leading up to the morning rush hour Friday.
The accident happened just before 4 a.m. at St. Charles Road in Berkeley, according to authorities.
Chicago fire officials said they were called to the scene for an emergency response just after 5 a.m.
All lanes of northbound I-294 were shut down due to the fire and clean-up between the Eisenhower Expressway and North Avenue. The exit ramp from the Eisenhower Expressway to I-294 was also being blocked.
Illinois State Police said the driver of the semi suffered minor injuries, but was able to exit the cab during the explosions. It was not immediately clear what caused the accident.
By 7:30 a.m., two lanes of the roadway had reopened.
