It's been a long road to recovery for many of the people who survived the horrific pileup on Interstate 75 two years ago.

Shelsie Ballew slammed into a semi, her Ford Explorer caught fire, and she barely escaped.

What she remembers most is the thick blanket of blinding fog.

"You could hear people screaming, you could hear people crying, but you couldn't help because you couldn't see anything. You just didn't have anywhere to go," she said.

Ballew survived the pileup that killed 11 people on the stretch of I-75 that runs through Paynes Prairie.

"My back kills me everyday," she said.

As Ballew and others continue to fight lawsuits as a result of the crash, state Department of Transportation officials are getting ready to put $2.1 million worth of technology in the area, to prevent another tragedy.

They are adding message signs, closed circuit television cameras to monitor the weather, visibility sensors, and a thermal camera in the middle of the prairie to monitor heavy fog.

"I really hope that this protects people in that area from now on," said Ballew.

Construction will begin in February, according to officials.
