Two people were taken to the hospital Saturday, Jan. 9, following a wreck on Interstate 985 in South Hall involving an overturned tractor-trailer carrying sawdust and three passenger vehicles, authorities said.

Minor injuries were reported, said Derreck Booth, Hall County Sheriff’s Office spokesman, adding that the call came in around 12:40 p.m.

The preliminary investigation indicates that traffic had slowed due to debris in the road, and a chain-reaction, rear-end crash involving the four vehicles occurred, Georgia State Patrol Cpl. Bronson D. Taylor said in an email.

“The tractor-trailer overturned onto its right side and came to rest across the northbound lanes blocking the roadway,” he said.

The investigation continues, and charges are pending, Taylor said.

Northbound I-985 lanes are shut down just north of the Friendship Road/Exit 8 exit ramp. Hall deputies were expected to keep the lanes closed “for an extended period of time for cleanup,” Booth said.

Traffic was being diverted off I-985 onto Friendship Road/Ga. 347.
