Fire and emergency crews were dispatched to the 2300 block of Douglas Run Road in Elizabeth just after 9:30 p.m. for a report of a tri-axle truck going over the hillside.

A hazmat team has been dispatched after first responders reported the spill into the river.

No information was available regarding injuries in the crash, according to an Allegheny County 911 supervisor.
