A Rawlins woman is dead after being struck by a freight liner truck in Carbon County.

The Wyoming Highway Patrol says just before 6pm on Thursday, June 18th, 44-year old Shelly Yoho was working as a flagger, in a construction zone on Interstate 80, about 15 miles west of Elk Mountain.

A freight liner truck pulling two trailers was going westbound in that area, when it started to drift onto the shoulder for unknown reasons.

The truck hit a bridge guard-rail, struck Yoho and then went into a ditch.

Yoho died on the scene from injuries that she sustained.

The driver of the truck, 50-year old Karama Leota of West Valley, Utah, was arrested for aggravated vehicular homicide, reckless driving, and failure to maintain a lane of travel.

The Wyoming Highway Patrol is investigating driver fatigue or distracted driving, as possible contributing factors in the crash.

The speed of the truck at the time of the incident is unknown.

The construction zone on I-80 has single lane travel, with both directions of traffic, traveling in the westbound lanes.
