Authorities said the wintry weather was not to blame for a collision on Ga. 400 Thursday that claimed the life of a Dawsonville man.

John Ivar Brothen, 51, of Northeast Cove Road, was walking south in a northbound lane of the highway when he was struck by an oncoming 2002 Honda Odyssey.

The driver of the van, Kimberly Hunsucker, of Dawsonville will not be charged, according to Georgia State Patrol trooper Todd Hinson.

Hinson said Hunsucker was traveling north on Ga. 400 when she struck Brothen just south of Edna Noblin Road. Her 16-year-old son was also in the van.

Neither was injured in the crash, which occurred about 5:45 p.m.

Hinson said Brothen hit the Hunsucker's windshield and died on the scene.

"About one minute before the wreck, there was a call to 911 saying a man was walking on Ga. 400. We were en route when he was hit," Hinson said. "We're not sure, but he could have been walking to the store on Henry Grady."

Ga. 400 was shut down for about an hour and half as crews cleared the wreckage.

While authorities say the wreck was not the result of winter weather, a Dawson County sheriff's spokesman said there were close to three dozen wrecks caused by icy conditions starting around rush hour Thursday afternoon and into Friday morning.
