CORTLAND COUNTY, N.Y. -- Sheriff's deputies are trying to figure out what caused a tractor trailer to go off the highway on Interstate 81 Tuesday morning. The Little Debbie truck was traveling south at about 6:30 a.m. when it crashed through the guard rail and slid down the embankment.

The left lane of the highway was shutdown at exit 11 for several hours while crews got the truck back onto the highway.

There's no word yet on any injuries.
