“Although the opening in the concrete barriers allowed the Acura to enter the work zone after losing control, the Acura’s excessive speed was the key factor that determined how far the vehicle traveled into the work zone as it overturned, resulting in the worker fatalities,” the report says.
The NTSB also noted how the State Highway Administration modified work zone safety since the crash, including closing adjacent lanes and blocking work zone openings with protection vehicles.
