A person was killed Wednesday evening in a crash on the Eisenhower Expressway in Chicago's western suburbs.

The crash shut down the expressway in both directions on the boundary of Maywood and Broadview.

State police were called to a multi-vehicle crash on the eastbound side of the expressway at 25th Avenue at 7:02 p.m.

After several vehicles crashed on the eastbound side, someone from one of the cars went flying over the center median and was struck and killed by a vehicle on the westbound side, state police said.

Both the eastbound and westbound Eisenhower were shut down between 25th Avenue and Mannheim Road, state police said.

The crash and shutdown caused a major traffic backup.

There was no word Wednesday night on what may have caused the crash, or on the identity of the victim.
