Work continued on Interstate 55 cleanup Tuesday after a massive pileup of vehicles kills six people on Monday.

The accident was south of Springfield and involved more than 80 vehicles and injured at least 30. Illinois State Police Major Ryan Starrick says the interstate will be closed for a portion of today as the investigation and cleanup continues.

In the aftermath, first responders are sharing firsthand accounts of the tragic accident. ISP Lieutenant Colonel Chris Owen says it was a zero-visibility situation along the interstate.

Illinois State Police Director Brendan Kelley says the victims are unidentifiable and they are looking for help.

Starrick says there were more than 30 agencies that came to assist during the crash.
