Pigs ran loose on a metro highway after a semitrailer truck that was carrying 50 hogs overturned, causing an hours-long shutdown Friday morning in Minnesota on Interstate 694.

State troopers tried to corral several loose pigs that cameras showed running through traffic, the Star Tribune reported.

The truck tipped over around 7:35 a.m. and caused morning rush hour traffic to back up for more than a mile, Minnesota Department of Transportation cameras showed.
