Emergency personnel responded about 10 a.m. Wednesday to a vehicle crash on Woodland Ridge about a half mile east of Bluff Road in Valmeyer.

The Monroe County Sheriff’s Department said a 2005 Chrysler Town & Country driven by Catherine Martin, 71, of Valmeyer was traveling west on Woodland Ridge when it lost control for unknown reasons, hit a guardrail and struck an embankment before rolling over.

Martin was transported by ambulance to St. Anthony’s Medical Center in St. Louis County for treatment of unspecified injuries.
