The 20-year effort to build a bicycle-pedestrian path through coastal Georgia from Savannah to St. Marys has been given a boost by the 2016 Legislature. The Georgia Department of Community Affairs received $100,000 to pass on to the Coastal Regional Commission, as project manager, which will oversee an engineering study to verify the 155-mile route linking South Carolina to Florida through Georgia’s six coastal counties. Already, 24 percent of the route is existing or funded for construction.
