A Georgia transportation official said a hurricane would cause chaos on South Georgia's roads, with out-of-state drivers flooding the area and causing congestion when a smooth evacuation is needed most.
Georgia, Florida and Alabama don't have a uniform plan for state evacuation routes if there were a hurricane.
Engineer Bryant Poole said motorists from Florida and Alabama wouldn't necessarily use the same roads as Georgians if there were a large-scale evacuation.
Poole said residents of neighboring states who try to head inland from the coast might end up using other roads that funnel them into small South Georgia towns.
More than $5.7 million in gates, radios, cameras and reversible interstate lanes have been installed in Georgia.
Meteorologists are predicting a below-average season for 2002, calling for seven to 10 named storms, of which four could develop into hurricanes. The 2002 hurricane season runs through November.
