Authorities say a woman was killed in a single-vehicle rollover crash on Interstate 90 near Drummond.

Highway Patrol Sgt. Art Collins says the woman was driving west from Helena just after 5:30 a.m. Tuesday when her station wagon drifted off the side of the road and into the median. Collins says the vehicle rolled when the woman overcorrected, and she was pronounced dead at the scene.

She was alone in the car, and her name has not been released.
