One person was seriously injured during a rollover accident Saturday evening, on the southern outskirts of Council Bluffs. The Iowa State Patrol says 46-year old Cynthia Devault, of Council Bluffs, who was not wearing a seat belt, was flown by LifeNet helicopter to Creighton University Medical Center in Omaha following the crash on Interstate 29 southbound near Lake Manawa, at around 6:10-p.m., Saturday.

Officials say for reasons unknown, Devault’s 2007 Chevy Impala swerved to the right across both lanes of traffic and entered the southbound ditch before rolling up and over a dirt berm and coming to rest on its top.

The accident happened at around the 46.25-mile marker.
