Tybee Island Depot The Central of Georgia depot at Tybee Island can be seen in this old postcard, published sometime around 1910. Although this building is gone, the depot at the other end of the line in Savannah still exists. Tybee Island is a city of 3,500 on the island of the same name. It lies about 15 miles east of Savannah.   Georgia's Railroad History & Heritage. Copyright, Steve Storey.
