A new bridge will be built over Interstate 985 as part of the planned HOT lanes extension on Interstate 85 from Old Peachtree Road to Hamilton Mill Road in Gwinnett County, a 10-mile stretch that skirts past I-985. “Express Lanes bridges are just bridges with a specified use, nothing special about their design or construction,” said Teri Pope, district spokeswoman for the Georgia Department of Transportation. Two such bridges are part of the current Express Lanes on I-85 between Old Peachtree Road and Chamblee-Tucker Road in DeKalb County — one at Ga. 316 east and I-85 north and one at Ga. 316 west and I-85 south.
