RALEIGH, N.C. (AP) — Police say a truck crash stranded thousands of piglets and drivers on a North Carolina highway.

Authorities say the tractor-trailer carrying more than 2,000 piglets overturned Tuesday on Interstate 40 south of downtown Raleigh, causing damage that triggered traffic problems for hours. They said a number of pigs died, but an exact figure wasn't available.

The police report said the truck was headed west on I-40 about 10:30 a.m. when a car changed lanes in front of it, leading to a collision. According to the report, the tractor-trailer went off the interstate, across an access ramp and hit a guardrail, causing the rig to overturn.

The truck was removed from the scene, but officials said some closures would stay in effect into Tuesday night as road repairs continued.

No serious injuries were reported.
