A semitrailer rolled over Tuesday afternoon on the Dan Ryan Expressway, causing significant delays until the crash could be cleared.
The semi rolled over about noon in the outbound lanes of Interstate 94 south of 71st Street, possibly when the load it was carrying shifted, according to Illinois State Police.
No injuries were reported, but the driver was taken to a hospital as a precaution, police said.
All lanes were back open by 1:40 p.m.
