A Forsyth County woman is in critical condition after a serious wreck that occurred overnight on Hwy. 20 and the northbound entrance ramp to Ga. 400, according to public safety officials.

According to Division Chief Jason Shivers of the Forsyth County Fire Department, at about 7:45 p.m. on Wednesday evening a Chevrolet sedan traveling eastbound on Hwy. 20 attempted to make a left turn onto the northbound entrance ramp of Ga. 400 when it was struck broadside by a Honda minivan traveling west on Hwy 20.

Shivers said that the impact of the crash completely rolled the sedan and trapped the vehicle’s occupant, a woman from Cumming, inside with critical injuries.

“The victim was trapped inside her car, and had to be extricated by firefighters,” Shivers said.

The driver of the Honda minivan received minor injuries in the wreck, while one passenger of the minivan was seriously injured. Due to the extent of their injuries, both individuals were taken to the nearest trauma center at North Fulton Hospital for treatment, Shivers said.

Westbound lanes of Buford Highway were closed for about one hour while the incident was cleared and investigated, Shivers said.

Law enforcement authorities are still investigating the cause of the crash, according to Cpl. Doug Rainwater of the Forsyth County Sherriff’s Office, but they believe that the Honda minivan had a green light, while the Chevrolet sedan was turning left with a flashing yellow light.

Rainwater said that they see many accidents of this type in that area.

He said that their Traffic Specialist Unit will be investigating the accident to determine its cause and whether charges are warranted.
