PITTSBURGH (KDKA) – A tractor-trailer accident on Interstate 79 had a major impact on traffic Thursday.

It first slowed down the morning rush hour commute and lasted well into the evening commute.

According to police, the truck hit a jersey barrier and overturned on the southbound side of I-79 near the Neville Island Bridge.

As a result of the crash, part of the truck was left dangling over the Route 51 overpass.

The truck was hauling a food additive and part of the load spilled onto Route 51. The substance is not toxic, but can be irritant to the eyes and throat.

“It’s used for pool filters, it’s a non-hazardous irritant,” said Robinson Township Fire Chief Kenneth Kisow. “It’s an irritant on your throat. That’s about all it is.”

As a result, I-79 south and Route 51 were closed in the area of the crash. Traffic was detoured onto Route 65.

However, Route 51 has reopened as of Thursday evening and one lane of I-79 south has also been reopened.

Traffic was gridlocked on I-79 miles away, as well as along the parkways.

Fortunately, there are no reported injuries.

Police say an accident reconstruction team is on the scene and will determine if speed was a factor in the crash.

Although, State Police Tpr. Robin Mungo said the driver was likely going too fast.
