June 19, 2013 13:25Traffic Division officers have conducted a preliminary investigation into this morning's crash on I-84 westbound to I-5 northbound.
Investigators have determined that a 2009 Nissan Versa, driven by 22-year-old Jordan-Ashlee Sylvester of Portland, was driving in the right lane of the ramp and switched to the left lane with the intent of continuing on I-5 northbound.
A 2010 Mack Tractor with a 53' cargo trailer, driven by 67-year-old David Lee Sitton of Arlington, Oregon, was in the left lane when the Nissan Versa collided with the right front tire of the tractor, causing the Nissan to swerve to the right and hit the concrete barrier. The tractor-trailer swerved to the left, rode up and over the 4' railing and drop 49' below to the Union Pacific Railroad property below the freeway. The Union Pacific Railroad office building sustained some damage from the falling truck.
Ms. Sylvester was not injured during the crash. She remained at the scene and cooperated with investigators. She was not impaired by drugs or alcohol. A passenger in her car was transported to a Portland hospital with non-life-threatening injuries.
The truck driver, Mr. Sitton, remains in a Portland hospital in serious condition. Mr. Sitton's family is requesting privacy at this time.
No citations have yet been issued and the case remains under investigation.
The tractor-trailer is owned by Walsh Trucking Company in Troutdale, Oregon.
