A Level 2 Hazmat spill on Interstate 55 (I-55) in the south suburbs of Chicago led to the closure of all southbound lanes on Friday, according to multiple reports. The Illinois Department of Transportation, along with Illinois State Police, confirmed the incident was due to a hydrogen peroxide leak from a disabled semi. The spill occurred near La Grange Road and caused significant traffic disruptions, including a major backup observed by SkyCam 9. Although the northbound lanes near Hodgkins were briefly closed, they were reopened later in the day. Cleanup efforts were underway throughout Friday, with all lanes, both southbound and northbound, near LaGrange Road eventually reopening by 5:44 p.m. after the disabled semi leaking the chemical was addressed.
