On February 1st, 2018 a fatal crash occurred at milepost 48 on Interstate 80 near Lyman, Wyoming.

A pickup was traveling eastbound on Interstate 80, when it drifted off of the highway to the left and struck a delineator post. The driver steered the truck to the right in effort to re-enter the roadway. He then collided with the median side of the bridge deck guardrail face. The pickup then traveled along the bridge deck before it rolled over the guardrail and landed on it's roof, on the I-80 Business Loop below.

At about 6 a.m., a passer-by on I-80 Business Loop saw the crashed pickup and called 911 and Troopers were sent to the scene.

The adult female passenger, identified as 30-year-old Green River, Wyoming resident Kymbrlee Smith, despite properly wearing her seat belt, was pronounced dead at the scene. The adult male driver, identified as 31-year-old Green River, Wyoming resident Samuel Smith, who was also properly wearing his seat belt, was taken by ambulance and then helicopter to the University of Utah Medical Center. He is currently in critical but stable condition due to head trauma.

A one-year-old child who was in a child safety seat; a three-year-old who was in a child safety seat; and a 10-year-old who was wearing his seat belt were taken to the Evanston Regional Hospital where they were treated and released to family members.

Fatigue is being investigated as a leading cause of this crash and during the investigation it was determined that it happened around 2:00 a.m.
