The Yreka Area California Highway Patrol reported that a man from Westminster, Calif., was transported to Redding for treatment of major injuries after the Chevy Volt he was driving northbound on Interstate 5 went airborne at Julien Creek north of Grenada and collided with a concrete abutment Friday afternoon, Oct. 6.

As described in a CHP news release:

Jason Kaiser, age 48, “was driving a black 2013 Chevy Volt northbound on I-5 in the No. 2 lane at an undetermined speed. For reasons still under investigation, the Chevy Volt left the right side of the roadway and was driving on the gravel shoulder. It struck a reflective paddle marker, the Julien Creek Bridge sign, and then took flight over the barbed wire fence. The Chevy grazed a vertical concrete bridge pillar while still airborne, prior to impacting the north concrete abutment. After impact with the abutment, the Chevy Volt spun underneath the bridge out of view from the freeway.

“Numerous witnesses stopped to check on Kaisers welfare and assisted with medical aid. CHP personnel from the Yreka CHP Office arrived on scene and began medical aid for Kaiser until CalFire and Mount Shasta Ambulance arrived on scene. LifeNet Medical Helicopter was requested by CHP due to the major injuries sustained. LifeNet transported Kaiser to Mercy Medical Center, Redding, for treatment of major injuries.”

The cause of the collision is under investigation, and witnesses are asked to please contact the Yreka CHP Office at (530) 841-6006.
