HAMMOND, Ind. — Two people were airlifted and a woman faces driving while intoxicated charges after a multi-vehicle crash on I-80 in Northwest Indiana early Saturday morning, Indiana State Police said.

Rivianna Gilmore, 33, of Calumet Park, faces multiple felonies of operating while intoxicated causing serious injury, endangering and multiple other misdemeanors.

According to Indiana State Police, around 4:14 a.m., a black Nissan struck an arrow board sign on the right shoulder that warned traffic of an approaching lane shift.

The arrow board landed in the travel portion of the roadway which caused two other crashes when drivers were attempting to avoid debris from the initial crash.

Troopers said the driver of one of the vehicles was pinned to their van and had to be extracted and airlifted to Chicago for life-threatening injuries.

A second driver, who was operating a black GMC pickup, was also later air-lifted to Oak Lawn for treatment of serious injuries.

The third driver received minor injuries.
