MARIETTA - Icy roadways were prevalent around the county Friday morning, and in one case forced two law enforcement officers to jump over a bridge in west Cobb to escape a careening car.

The cold will continue through the weekend, though Accuweather is not predicting further precipitation either day.

About 9:35 a.m. Friday, a Cobb Sheriff's deputy was driving south on Barrett Parkway between Villa Rica and Macland roads and slid into a retaining wall.

An off-duty Cobb Police officer, R.L. Turman, stopped to help when the driver of a PT Cruiser lost control on the same stretch of the roadway. The two officers leaped over the bridge to an embankment 20 feet below to avoid being hit by the car. They were taken to area hospitals with non-life-threatening injuries. Both were released by afternoon.

Elsewhere across the county, the below-freezing temperatures kept a lot of people at home. Both Marietta and Cobb County Schools were closed, as were Chattahoochee Technical College, Kennesaw State University, and Southern Polytechnic State University.

Craig Wilkinson, who lives in the Meadow Chase subdivision off Sewell Mill Road in east Cobb, said he saw a lot of children playing outside.

"A lot of kids are sledding down their sloped driveways," Wilkinson said. "I went out around 5 this morning to walk the dogs, and I about killed myself. I didn't realize it had iced as bad as it did."

Austell Mayor Joe Jerkins said his city's fire crews responded to a car fire near Maxham Road and Veterans Memorial Highway before daybreak on Friday, and one fire truck slid into another. No one was injured and the trucks were not heavily damaged, Jerkins said.

"They pulled both fire trucks up on a hill, and after about 40 minutes, when they had been spraying water, the truck just started sliding down the hill and hit our other truck," he said. "It went about 40 feet."

Cobb County transportation crews had 22 trucks on the roads spreading salt and sand. There were a few temporary road closures early in the day, but all were reopened by afternoon.

David Montanye, director of Cobb DOT, urged drivers to be cautious and said, "We are working around the clock to address icy road conditions which are prevalent around the county. Crews are scheduled to work into mid-day Saturday and we will re-evaluate our work plan based on conditions at that time."

Sgt. Dana Pierce of Cobb Police said more than 300 car accidents had been reported since 4 p.m. Thursday, including more than 40 with injuries, though none critical.

"And that number is climbing as we speak," he said late Friday afternoon. "I don't know how to overemphasize to people to slow down."

There were no power outages among Atlanta Gas Light, Cobb EMC and Marietta Board of Lights and Water. At WellStar hospitals, no surgeries had to be canceled, and many staffers stayed past their shifts until other team members could make it in.

Acworth Mayor Tommy Allegood said traffic was moving pretty good in his city.

"There's not a lot of people out on the roads," he said.

Bill Katin was one of those keeping close to home in Powder Springs.

"I figured if I didn't have to get out, I wouldn't. My daughter, though, is out and about," Katin said. As for the snow, "I think the sun has melted most of that away," he said.
