The northbound side of Interstate 35W in Fort Worth was closed overnight Monday due to a fiery crash and a large fluid spill, police say.
The crash happened at about 8:15 p.m. Sunday along northbound I-35W, just north of East Morningside Drive, police said.
Pictures posted on social media showed drivers slowed behind an 18-wheeler that had been engulfed in flames. The truck appeared to be blocking multiple lanes of traffic.
A MedStar spokesman said three people had minor injuries that were treated at the scene. A fourth person was sent to John Peter Smith Hospital with injuries that were not life-threatening, MedStar said.
No further information was immediately available.
All lanes were open by 2:45 a.m., according to the Texas Department of Transportation.
