Traffic is moving again on eastbound Interstate 80 after a crash Thursday morning near Harlem Avenue in Tinley Park.
The crash happened about 6:45 a.m. and involved at least two vehicles, Illinois State Police said. At least one person was injured in the crash, but none of the injuries were thought to be life threatening.
Two lanes were closed for about 20 minutes as emergency crews worked to clear the crash, state police said. They have since been reopened.
