Montana Highway Patrol troopers respond to a fatal crash on Interstate 90 near Laurel.
A 36-year-old Park City woman was killed when her sport utility vehicle rolled over west of Laurel on Sunday morning.
The crash was reported at 8:44 a.m., said Montana Highway Patrol Trooper David Munson.
The SUV was eastbound on Interstate 90 near mile marker 433 when the vehicle lost control, he said.
The vehicle rolled over a guardrail, took out half of a large highway sign and rolled to the bottom of a steep ravine, Munson said.
The driver was the only person in the vehicle at the time of the crash.
