A fuel spill shut down Interstate 30 westbound at Sylvan Avenue near downtown Dallas on Thursday afternoon.
About 200 gallons of fuel flooded I-30 during a crash involving a sedan that rear-ended a dump truck, officials said.
The crash punctured the truck's fuel tank, spilling its contents, they said. Video from the scene showed the mangled car on the fuel-soaked road.
The wreck backed up traffic for more than 8 miles.
Officials periodically allowed the right lane of westbound traffic to pass but it was unclear when I-30 would completely re-open.
No injuries were reported.
