Aid and law enforcement were dispatched at 2:30pm today, May 10th, to the northbound lanes of I-5 north of the Custer Rest Area for a report of a rollover crash.
First responders arrived to find a commercial box truck on its side and facing south in the on-ramp lane leading from the rest area near milepost 268.
Traffic was being allowed past in the left lane but by 3pm the back up stretched 2 miles to the Grandview Road interchange.
According to Washington State Patrol Trooper Heather Axtman, a preventable medical condition led to the rollover and the driver was cited for negligent driving. A tow truck had been dispatched to the scene as of 3pm but it was unknown how long it would take to upright the truck and clear the lane.
The right lanes remain blocked as work continues to remove the truck.
