Southbound lanes on the Dan Ryan Expressway (I-90/I-94) were shut down for hours and police were investigating after a woman walking along the highway was struck and killed, the Illinois State Police said.
The incident occurred around 2:25 a.m. near Chinatown, in the outbound lanes of the Dan Ryan Expressway between 18th Street and the Stevenson Expressway (I-55), ISP said.
According to the Chicago Fire Department, a 30-year-old female was pronounced dead at the scene.
ISP told NBC Chicago the woman was involved in a previous, minor crash and had gotten out of her car. She was then struck and killed by another vehicle, ISP said.
Early Tuesday, traffic was still backed up and building, and a detour was in place. NBC 5 Traffic reporter Kye Martin also reported that onlooker delays in the inbound lanes were forming.
Martin warned south side commuters that the investigation and the reroute were creating a "major traffic impact right at the Stevenson interchange."
At 6:50 a.m., all lanes of I-94 southbound at 18th Street had reopened, the ISP said.
