The motorcycle driver, who taken to a hospital by helicopter, was an off-duty Roswell Police officer, said Sgt. Dana Pierce, spokesman for Cobb County Police.
The accident was caused by a black Toyota Camry, Pierce said, and happened when the car collided with motorcycle and threw the driver into some other vehicles.
The police officer was riding his personal motorcycle at the time, and might have just completed a funeral detail or other job, he said.
Woodstock Fire Chief Dave Soumas said the wreck involved two or three cars, and his department assisted Cobb County officials on the scene.
Both northbound and southbound on Interstate 575 were shut down while emergency personnel set up a helicopter landing to airlift the motorcyclist from the scene of the wreck about 2 p.m., and Soumas said he did not know the driver’s condition.
“Traffic is messed up in the area while the investigation is ongoing,” Soumas said about 2:45 p.m. Friday. “Both southbound lanes are opened now, but avoid northbound while they’re investigating. However, traffic is moving slow, even southbound.”
Soumas said when the fire department left the scene just before 2:45, Interstate 575 northbound was still shut down as officials investigated the scene of the crash.
Soumas said although the wreck happened in Cobb County, Cherokee officials were assisting the rescue efforts.
“We assisted Cobb, this is well inside of Cobb County on 575,” Soumas said. “Cherokee County handled one of the patients, they drove one of the patients to the hospital. We helped Cobb with a landing zone.”
