Mesquite police say I-20 reopened early Thursday a few hours after a pickup going the wrong direction slammed into an SUV. Authorities say two adults and two children in the truck died at the scene.
The Department of Public Safety says the driver of the SUV also was dead at the scene.
A DPS trooper spotted the pickup going the wrong way and attempted to stop the vehicle just before the accident late Wednesday.
Names of the victims were not immediately released.
