Pender County officials tell news outlets the truck's cargo was sent onto U.S. Route 17 northeast of Wilmington near the New Hanover-Pender county line. The spill happened shortly before noon Tuesday and delayed traffic into the evening rush hour.
Firefighters posted a photo on Facebook of the more than a dozen yellow containers on their sides.
An official told The StarNews of Wilmington the load could've been waste that was thrown away.
Temperatures were around 80 degrees so it's unlikely the dough would've baked on the road.
It is unclear where the truck came from or where it was going.
