Authorities say a truck carrying more than 150 pigs tipped over after jumping a curb on the edge of Riverside Thursday night.
Sioux City Police say the accident happened just before 9pm in the 5200 block of Military Road near Sacred Heart Church.
Investigators say the driver failed to negotiate a curve in the road and the truck toppled.
Over two dozen of the pigs were dumped out of the truck in the accident.
Animal control officials helped round up the pigs.
The driver was uninjured.
The pigs were from Ireton, Iowa, and were being transported to Missouri.
