A 35-year-old Livingston woman died Friday night after rolling her vehicle on U.S. Highway 287 near mile marker 99.
The woman was traveling southbound on U.S. 287 in a Subaru Legacy when, "for unknown reasons," she drifted off the side of the road, according to a Montana Highway Patrol dispatcher.
The woman overcorrected, crossing into the northbound lane. The vehicle spun around once and then rolled.
The crash occurred at 10:37 p.m. The dispatcher described the road conditions as "bare and dry."
At this time, it's unknown if alcohol was a factor, but speed was not, the dispatcher said.
As of 12 p.m. Saturday, no further information was available.
