The Port of Savannah, on the coast of Georgia, is the fourth-largest seaport in the United States. In recent weeks, it has faced a consistent backlog of roughly 20 ships awaiting berth space as a result of a significant increase of incoming container ships. The logjam in Savannah reflects similar congestion at other large U.S. ports - including Los Angeles, Long Beach, and New York / New Jersey - which experts believe is the result of many retailers rushing to restock inventory before the holidays.
