Rowlett police said at least one person was killed and others were injured Saturday night in a major accident on Interstate 30 near the Horizon Road exit in front of the Trend Tower office building.
Wet weather is believed to be a factor in the wreck, which shut down traffic on the busy highway for hours.
The police department said the 6:30 p.m. wreck involved several 18-wheelers and passenger cars.
Police said a westbound big rig crossed through the concrete median barrier into the eastbound lanes, "causing further collisions." Witnesses said it was raining hard at the time.
"The accident resulted in one confirmed fatality," the department said on Facebook. "Other drivers were transported to local hospitals for treatment."
The identities of the victims have not been released.
"Lane closures will be anticipated for an extended period of time due to the size of the accident scene and the ongoing investigation," police said.
