Editor's Note: A previous report stated that both the driver and passenger died in the crash, but that incorrect information came from police. The passenger is still alive.

GRAND PRAIRIE -- One person was killed and another was injured in a Grand Prairie crash early Wednesday morning.

Police say the incident happened in the westbound lanes of Interstate 30 near the President George Bush Turnpike interchange at about 3:30 a.m. 

A truck was heading west when it veered onto the outside shoulder, police say, causing it to strike more than 200 feet of guardrail and wooden posts. 

The truck then went up on a wall and fell onto the northbound lanes of the PGBT, landing on its roof.

The driver was pronounced dead at the scene of the crash. The passenger was taken to Methodist Dallas Medical Center in critical condition.

Northbound lanes of the PGBT are closed in that area.
