Tickets are $30 for members of any of the three chambers, or $35 for nonmembers.James McCoy, president and CEO of the Forsyth chamber, said the event is largely geared toward businesses and individuals with high stakes in the future of the corridor.“I suspect we’ll have 100 folks or so, but what’s going to be more important is the real focus on making sure that folks from Forsyth, Dawson and Lumpkin counties who consider Ga. 400 to be the most important to them are there and are engaged,” he said.McCoy noted the event will primarily consist of a panel discussion by representatives from the State Transportation Board of Georgia, the state Department of Transportation, and the State Road and Tollway Authority.“There will be some opportunity for feedback from the audience,” he said. “But it’s really more intended to be a discussion among the panelists about the importance of 400 and what we can all be doing to better work together for the future of Ga. 400.”Linda Williams, president of the Dawson County Chamber of Commerce, said she’s enjoyed the opportunity for the three counties to work together on the event.
