A truck driver from Redmond was injured early Friday morning when his rig crashed head-on into a tree off Highway 62 near Prospect in Jackson County, Oregon State Police reported.
OSP said it is continuing the investigation into the cause of the crash.
Around 5:15 a.m., a Les Schwab commercial truck driven by Gary D. Flory, 50, of Redmond, was heading west on Highway 62 near milepost 50, troopers said.
For what OSP called "an unconfirmed reason," the truck and two trailers loaded with tires traveled off the highway where the truck crashed head-on into a tree.
Troopers said Flory was seriously injured and trapped inside. It took fire personnel from Prospect Rural Fire Protection District about 45 minutes to extricate him from the truck.
Flory was flown by air ambulance to Asante Rogue Regional Medical Center in Medford, where he was listed in fair condition late Friday afternoon, according to a nursing supervisor.
OSP troopers from the Central Point Area Command office are continuing the investigation. Trooper Ryan Neuenschwander is the lead investigator.
OSP was assisted at the scene by the Jackson County Sheriff's Office, Prospect Rural Fire Protection District and ODOT.
ODOT remained on scene Friday afternoon, coordinating vehicle removal. According to TripCheck.com, motorists should use caution and expect delays (near Ginko Basin Road - between Prospect and Union Creek) as salvage operations have begun to offload cargo and remove the vehicles.
Travelers should expect single lane traffic controlled by flaggers and intermittent closures of up to 15 minutes. Traffic updates will be posted on TripCheck.com.
