Bullard Police Chief Gary Lewis said the accident occurred about noon when a DS Disposal dump truck crossed the highway at County Road 3801 and was struck by an oncoming East Texas Support Services van.
The driver of the dump truck and three women passengers in their 60s were taken to East Texas Medical Center in Tyler, Lewis said. Two were taken by ambulance and two by helicopter.
Lewis confirmed one died at the hospital, but the name was not released as of Monday evening pending notification of next of kin.
Lewis said the dump truck was struck broadside in the middle of the driver's side. He said the truck was not heavily damaged, but the jaws of life were used to cut the van's roof and doors off to get passengers out. He said the dashboard also was cut to get the driver out of the vehicle.
Lewis said the accident is under investigation.
