All eastbound lanes and westbound lanes were closed creating multi-mile delays in each direction. The exit from the Garden State Parkway to Route 280 West was closed.

Lt. Gov. Sheila Oliver in a statement said "our thoughts are with the State Troopers, fire personnel, EMS professionals, and pedestrians who were injured in this morning’s incident" and wished them a quick recovery. She said in a tweet that she visited the troopers at University Hospital in Newark.

"While this is an ongoing investigation, it should remind us all of the dangers our first responders can encounter while performing their jobs on our roadways," Oliver said.

Oliver is the acting governor while Gov. Phil Murphy is on 10 day vacation out of the country.
