Authorities said a 42-year-old Cumming woman remained hospitalized Friday, two days after she and her son were injured in a single-vehicle wreck on Castleberry Road southwest of Cumming.

Lisa Polk and the boy, 11, are both in stable condition, according to Robin Stone, a spokeswoman for the Georgia State Patrol.

The crash occurred about 5:10 p.m. Wednesday, when the southbound Jeep that Polk was driving left the edge of Castleberry near Piney Grove Road, Stone said.

“She attempted to take corrective action to regain control, but was unable,” Stone said. “She went down an embankment, which is approximately 25 feet, and she overturned into a creek.”

It took firefighters about 20 minutes to free Polk from the upside-down Jeep, according to Forsyth County Fire Division Chief Kevin Wallace.

According to the state patrol report, Polk was flown to Grady Memorial Hospital in Atlanta with a broken neck.

Her son was taken by ambulance to the same hospital with “minor to severe cuts,” Stone said.

Both mother and son were wearing seat belts when the accident happened, according to the state patrol.

Polk received a warning for failure to maintain lane, Stone said. Speed was not a factor in the wreck.

No other vehicles were involved in the incident, which shut down Castleberry southwest of Cumming for more than an hour during the evening commute.
