The Florida Highway Patrol responded to a crash involving two tractor-trailers, a collision that freed pigs, which then wandered along the side of Interstate 95.
The crash occurred in St. Johns County.
The FHP said the cause of the collision between the two tractor-trailers is still under investigation.
When the tractor-trailers collided, it caused one tractor-trailer that was carrying pigs to overturn, causing the livestock to escape and wander along the road's edge.
The second tractor-trailer partially rolled over, the FHP said.
There are no reported injuries, but the FHP cautioned that some pigs might still be on the loose.
