Traffic is flowing again on eastbound Interstate 30 in Dallas after an early-morning crash near the Lawnview exit.
A big-rig overturned at about 3:45 a.m. Wednesday, according to the Texas Department of Transportation, and came to rest on its side blocking all four lanes of traffic.
Two tow trucks were able to upright the truck shortly after 6 a.m. About 45 minutes later, crews were able to clear the lanes and reopen the highway.
The remaining concern was diesel fuel that had spilled from the truck into White Rock Creek, which flows beneath the elevated highway.
A TXDOT official told NBC 5 that hazardous materials workers were working to minimize any effects of the spill.
It is not yet known what caused the crash, but the driver was taken away from the scene in an ambulance. The driver's condition is not known.
