The accident happened at about 6:15 a.m. on the eastbound ramp of Route 30 to Route 202 in East Whiteland Township.
Another truck to carry the pigs from the accident scene arrived just before 8:30 a.m., and Chopper 6 was overhead as workers were transferring pigs from one truck to the other.
The driver was not seriously injured during the accident in Chester County.
Police had that part of the highway closed for about 4 hours while they removed the pigs, put the truck back on all its wheels, and got all the vehicles out of the way.
