Illinois State Police said there were major traffic impacts following a three-vehicle crash in Northbrook near Dundee Road Monday afternoon.

State police said they were called to the scene in the southbound lanes of the Edens Expressway around 12:30 p.m. near milepost 30 at Dundee Road near Route 41.

Three vehicles were found at the scene, one of them off the roadway with severe damage, according to the Lake County Coroner's office.

An occupant of one of the cars — identified as Martin Maldonado-Velazquez, 60, of Waukegan — was rushed to Endeavor Health Highland Park Hospital, where he died in the emergency room.

An autopsy determined he died of blunt force injuries as a result of the crash, according to the Coroner's office.

All southbound lanes of I-94 were closed at Dundee Road following the crash. The Dundee Road southbound ramp to I-94 and the southbound lanes of Lake Cook Road to I-94 were also closed. 

Police did not say how long they expect the closures to last.

Forestway Drive, Skokie Boulevard, Waukegan Road, Green Bay Road, and even the Tri-State Tollway were gridlocked following the crash.

State police said the crash scene is still active and the investigation is ongoing. Drivers should seek alternate routes and are advised to avoid the area. Delays on I-94 south should be expected.

The inbound lanes of the Edens were finally reopening at 6 p.m.
