One person was seriously injured in a two-vehicle crash that occurred on northbound Interstate 5 Wednesday morning. The crash involving a white SUV and semi-truck occurred at around 4:15 a.m. near milepost 268, about four miles south of Woodburn. Oregon State Police said an investigation revealed a Chevy Tahoe was parked on the shoulder of I-5 when it was struck by a Peterbuilt truck and semi-trailer that had left the roadway for unknown reasons. Marion County Fire District #1 officials told FOX 12 it took 10 firefighters to take apart the Chevy to get a man out of the vehicle. The man was then life-flighted to Salem Hospital with critical injuries. The driver of the semi-truck was treated for minor injuries, according to OSP. The right lane of northbound I-5 was affected by the crash.
