A tractor trailer rollover happened Tuesday night, in Rush Township off of Route 322.
The tractor trailer was traveling down the mountain when the driver was allegedly going too fast and lost control.
The driver then went over a guardrail and 50 feet down an embankment, causing the tractor trailer to rollover multiple times.
The driver was thrown from the truck and eventually taken to UPMC Altoona by Port Matilda EMS.
An investigation is ongoing.
