LITTLE ROCK, Ark. (AP) -- Hogs on the highway aren't always motorcycles.

Arkansas State Police say a tractor-trailer rig hauling pigs overturned early Monday on a major highway and some of the four-legged hogs got loose.

The wreck and the roaming porkers closed a stretch of Interstate 430 connecting Little Rock to North Little Rock.

State Police spokesman Bill Sadler said morning commuters were detoured around the area as troopers and others tried to corral the escaped hogs.

The swine could weigh as much as 800 pounds each.

Authorities said the truck was carrying about 90 hogs. Some of them remained in the trailer while others made a break for freedom.
