HUMBOLDT, S.D. - A semi-truck caught fire Thursday on I-90 at the Humboldt exit.
Firefighters had to shut down the Humboldt exit while crews cleaned up.
The semi-truck was hauling a trailer full of pigs, but luckily, none of them were hurt. The driver was also able to get out safely.
A Schwan's truck driver stopped to give the firefighters free popsicles since it was such a hot day.
