The Oregon State Police says a wrong-way driver died in a head-on collision with a semi-truck Monday evening on Interstate 84 in Gilliam County. The OSP received word of a van traveling the wrong way in the I-84 eastbound lanes near milepost 141 east of Arlington on Monday at about 7:40 p.m. Minutes later, the van was reported to have crashed head-on into a semi tractor-trailer carrying vehicles. The OSP says a preliminary investigation revealed the van had traveled westbound in the eastbound lanes at about 55 to 60 miles per hour. The van crashed into the semi head on and came to a rest on top of the concrete center-line divider. The semi caught fire and became fully engulfed in flames, completely blocking the entire interstate for several hours. The driver and sole occupant of the van was pronounced deceased at the scene and his identity is being withheld pending notification to the family. The driver of the semi, identified as 24 year old California resident, was treated for non-life threatening injuries at the scene.
