I-49 Westbound on the Terry Bradshaw Passway (near Mansfield) is down to one lane.
Around 5:30 a.m., an engine of a Schlumberger truck caught fire.
The interstate was shut down, and the flames were quickly put out.
No word on injuries at this time.
Eastbound lanes are all open, but if headed westbound, be sure to allow extra time.
