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

John 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, said Georgia State 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 of the Hunsuckers were injured in the incident, which occurred about 5:45 p.m.

Hinson said Brothen struck the van’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,” Hinson said. “We were en route when he was hit.

“We’re not sure, but he could have been walking to the store on Henry Grady.”

Ga. 400 was shut down for about 90 minutes as crews cleared the scene.

Thursday’s collision may not have been weather related, but Dawson County Sheriff’s officials said the icy conditions of late last week contributed to about 90 wrecks.

No one was injured in 75 of the crashes, which occurred between the evening rush hour Dec. 15 and Friday morning.
