Interstate 84 Critical Injury Crash

(PORTLAND, Ore.) - Update Motorcyclist Dies From Injuries Sustained in Crash on I84

Oregon State Police (OSP), with the assistance of Portland Police Bureau (PPB), is continuing the investigation into a critical injury traffic crash that occurred Wednesday evening in the eastbound lanes of Interstate 84 at the 33rd Avenue exit ramp.

Congested and slowing traffic were present in the eastbound lanes during the presidential motorcade's procession on the westbound side of the freeway.

According to OSP Senior Trooper Jason Lindland and previously released information from PPB, on October 20, 2010 at approximately 5:51 p.m. a collision involving a motorcycle occurred on the Interstate 84 eastbound lanes at the 33rd Avenue exit ramp. A 2000 Yamaha motorcycle operated by Peter K. Gunderson, age 59, from northeast Portland, was eastbound when Gunderson failed to see that ahead traffic was slowing while the motorcade traveled in the westbound lanes.

Gunderson lost control, fell off the motorcycle and slid underneath a 2010 Chevrolet Camaro which was ahead of him in the left eastbound lane. The motorcycle came to rest near the center concrete barrier.

Lindland hasn't confirmed information regarding a reported fire.

Gunderson was transported by ambulance to Legacy Emanuel Hospital with injuries described as critical. He was wearing a protective helmet.

The Chevrolet's driver, LEEANNE C. GRIFFIN, age 38, from southeast Portland, was not injured.

OSP troopers assisting during the motorcade responded to the scene and took over primary investigation responsibility from PPB to help their department during the president's visit.

Portland Fire Bureau and ODOT also assisted at the scene. Eastbound lanes were blocked about one hour due to this incident.
