Overnight snow and icy conditions led to a jackknifed semitrailer Wednesday morning, but no major accidents.
Southbound lanes on Interstate 55 near U.S. Route 6 were completely closed for less than an hour while the semitrailer was removed.
State police said several vehicles were losing control in the morning on long stretches of I-55 and I-80 extending into rural areas of Grundy and southern Will counties because of icy roads and blowing snow. Hazardous areas were noted on I-55 from I-80 south to Dwight Road. On I-80, motorists were urged to take caution from Harlem Avenue west to Dwight Road.
The semitrailer that jackknifed was not far from another section of I-55 where icy conditions precipitated a chain of five accidents involving 13 vehicles Monday morning. That happened just south of U.S. Route 6 and in the northbound lanes.
Grundy County Sheriff Kevin Callahan said Wednesday morning deputies reported about a half-a-dozen motorists needing assistance in ditches all around the county.
No accidents and no injuries were reported as of Wednesday afternoon, he said.
