Overall, GDOT is paying for this $57.7 million contract - awarded to Marietta-based CW Matthews - to transform the state route from a two-lane roadway to a thoroughfare with four lanes and a raised median from Cherokee Street to U.S. 41 in Acworth.
Once complete by next fall, this 2.8-mile stretch of Ga. 92 also will include a 10-foot multi-use trail on the east side of the road, a 12-foot shoulder with curb and gutter and a five-foot sidewalk on the west side of the highway.
The project also calls for replacing the bridge over Lake Acworth, which will cost $21.7 million.
The two-lane state highway is used by about 24,000 cars each day.
When completed, the roadway is expected to carry 35,000 cars daily.
