By 11 a.m., all southbound lanes had reopened on the Dan Ryan Expressway. The 6:10 a.m. crash left debris on the Red Line tracks, which temporarily halted service. The rollover crash at 89th Street was still being investigated.
Police say the woman who died lost control of her gray 2004 Chevrolet Impala. Police say her car hit the inner wall that divides the Ryan and the L tracks. The car flipped onto its roof. When it crashed, it also knocked down the fence that divides the CTA tracks from the expressway. The fence debris fell on the tracks and was hit by a train, causing an electrical shortage on the tracks.
A tow truck was also hit during the accident. The driver was taken in fair condition to Roseland Hospital.
The deceased driver, 25, was not wearing a seatbelt, state police said, adding the Impala was traveling at a "high rate of speed" when the driver lost control.
