A semi truck carrying oil crashed Thursday evening, prompting both directions of Highway 431 to close.
It happened near the Flint River Bridge. Huntsville Police say the truck hit an embankment, flipped over the rail and caught fire.
HAZMAT crews were called in because of the oil. State troopers have since taken over the scene.
Police say Highway 431 northbound and southbound lanes could remain closed until early morning hours.
