The Port of Morgan City (Latitude: 29º41’28” North, Longitude: 91º12’00” West) is located on the Atchafalaya River which has its beginnings at the junction of Old River and the Red River in east-central Louisiana. Old River is a short connection between the head of the Atchafalaya and the Mississippi River. The Atchafalaya flows southward a distance of 135 miles and empties into the Atchafalaya Bay.

International Cargo can be received at the Port of Morgan City and prepared for overland shipment to U.S. markets. The Intracoastal Waterway System and the Inland rivers of the Upper Mississippi River Valley reach markets in 37 U.S. states.

Traffic between points in the southwest United States and the Upper Mississippi River Valley saves approximately 342 miles per round trip by using the Atchafalaya River rather than the alternate link of the Intracoastal via the Harvey Locks at New Orleans.
