HOUSTON, Texas (KTRK) -- The aftermath of an 18-wheeler fire is impacting traffic along a portion of the Southwest Freeway on Thursday morning.

Houston TranStar reported the heavy truck fire just before midnight on I-69 northbound at Bellaire Boulevard, causing some right and center lanes to close.

The fire is out now, but flames were visible coming from the big rig at around 3:30 a.m. A Houston Police Department officer told ABC13 the truck was hauling tomatoes and headed toward New Jersey before it caught fire.
