Interstate 45 was closed in both directions southeast of Dallas Thursday morning due to a fiery crash involving a semi truck that was carrying pigs.

The crash took place just after 6 a.m. Thursday. Images from the scene of the crash showed the truck turned on its side surrounded by scorched debris.

Some of the livestock was loose on the highway.

Details about the crash haven't been released. Just before 2 p.m. officials said the truck was turned upright, and there was more hazmat cleanup to do.

Southbound lanes of I-45 should be opened by rush hour.
