The dump truck overturned in the southbound outer lanes of the NJ Turnpike went down an embankment, through a guard rail and dumped a load of dirt in the right lane, according to NJ State Police.
The New Jersey Department of Transportation said the bridge on Route 571 will close Wednesday night between Tiger Lane in West Windsor and Faculty Lane in Princeton until sometime in the fall.
The ceremonial first ride on the replacement I-95 roadway was by firefighters from the first Philadelphia fire company that responded to the tanker fire that caused the overpass collapse.
