The Georgia Ports Authority is expanding the Port of Savannah's refrigerated storage space for poultry and other cargo that needs to be kept cold.

The agency's board approved the $4.75 million project Monday. It will consist of 20 container racks, each four stories tall, that will power refrigerated containers.

The new racks will expand the Savannah port's refrigerated storage by 45 percent, with total space for 1,536 cargo containers.

Port officials say poultry was the Georgia ports' fourth largest export commodity in fiscal 2011, with 1.6 billion pounds shipped overseas in cargo containers.

The Port of Savannah is the fourth busiest container port in the U.S.
