Troopers were dispatched to the area of mile marker 146 near the Bitter Creek exit at 2:03 p.m.

Christine Keller, 52, of Morton, Wash., was driving a 2018 Volvo semi-tractor and trailer east on I-80 when it drifted from the left lane into the median and collided with a box beam guardrail and overturned.
