The Terrebonne Port Commission's 680-acre site is located on Industrial Blvd. in Houma, La. The tract is one mile west of LA Highway 57 and the Houma-Terrebonne Airport. The Port of Terrebonne is located on the Houma Navigation Canal within one-half mile of its intersection with the Gulf Intracoastal Waterway. This location puts the port in a strategic position to take advantage of significant cargo flows and marine traffic on both waterways.
