ANDERSON, Ind. — Four people were injured in an 11-vehicle crash Sunday afternoon on I-69 northbound near Anderson that caused heavy traffic and multiple lane closures.

The incident occurred when 10 passenger cars were stopped on I-69 NB between Rangeline Road and Markleville Road, an area just south of Anderson, for a smaller crash a little ways up the road, according to Sgt. Scott Keegan with Indiana State Police.

An approaching semi-truck failed to see the stoppage and hit multiple stopped cars, ISP said.

A total of 11 vehicles, including the semi, were involved in the wreck. Four people involved in the crash were taken to local hospitals in stable condition and no fatalities were reported, ISP said.

As of 10 p.m. Sunday, the Indiana Department of Transportation confirmed that all southbound lanes of I-69 have reopened. Sgt. Keegan added that all northbound lanes are expected to remain closed for an additional 2 hours. The exit ramp is closed as well.
