A burning tractor-trailer shut down Interstate 77 in Mooresville on Tuesday morning as fire crews worked to clean up the mess.
The truck, which caught fire just after 3 a.m., was on the northbound side near the Brawley School Road overpass.
The Brawley School Road is currently under construction at mile marker 35.
Firefighters cut the roof off the trailer as huge flames could be seen shooting out of the roof.
Firefighter said the truck was carrying tightly packed clothes inside small boxes, which have contributed to the fire. Firefighters had to remove all the boxes to be able to put out the fire completely.
Officials said they think the truck scraped a barrier and possibly ruptured a fuel tank.
Fire officials said they called in a Hazmat crew from Charlotte because of the fuel spilled on the roadway.
Fire crews were able to put out the fire around 6 a.m. The delays lasted until shortly before 1 p.m.
Paramedics had to treat a firefighter on the scene for heat exhaustion. The driver of the truck suffered only minor injuries.
