Residents can have their say during the next month on state plans for construction projects intended to improve traffic on Ga. 400.

The State Road and Tollway Authority scheduled a series of public meetings to collect public comments on $67 million in projects proposed for Ga. 400. The projects are scheduled to be constructed from 2011 through 2014, the authority said.
