A tractor trailer rollover along I-80 in Marion Township, Centre County, is creating a traffic delay this morning. 
 
State Police say Jacksonville Road, north of the on/off ramps to I-80 is closed along with part of the I-80 westbound off ramp near Exit 161.
 
PennDOT is on scene working to clean up the area. 
 
Officials believe the driver was exiting I-80 at the 161 off ramp when he was going too fast. The road was wet and as a result the truck slid off the road, hitting an embankment, causing it to roll over. 
 
We’re told the truck was hauling dog food. 
 
The driver was not injured. 
 
The road is expected to be shut down for several hours.
