According to Ohio State Highway Patrol Trooper Larry Anderson, the single-car accident occurred near the intersection of Ohio 748 and U.S. 23 around 1:15 p.m.
Mary Freehill, 47, of Scioto Furnace, was traveling west on Ohio 748 when her 1991 Lincoln Towncar went off the right side of the roadway and struck a utility a pole at the intersection, troopers said.
Anderson said he didn't see any visible injuries on Freehill, but she was complaining of injuries to her wrist and of chest pains. The trooper couldn't say if the chest pain was from a heart condition or an injury from the crash.
She was taken to Southern Ohio Medical Center for treatment and was then taken to Grant Medical Center in Columbus. She was being treated in the hospital's emergency room and was in fair condition.
One passenger, Freehill's 11-year-old granddaughter, Audrey Smith, was treated for minor scrapes from the car's seat belt.
The wooden pole broke at the base, sending a highway safety light onto the roadway and knocking out a line to another nearby electric light.
Anderson said the accident is still under investigation, and a cause won't be determined until after he speaks to the driver.
