The Lake Charles Harbor and Terminal District (Port of Lake Charles) encompasses 203 square miles in Calcasieu Parish and accommodates 5 million tons of cargo annually at its public facilities. The Port of Beaumont is the second largest U.S. military port in the world where marine vessels along with 7,700 trucks and 24,000 railcars moved more than 3.2 million tons of cargo last year. Port of Port Arthur is strategically located midway on the barge shipping routes of the intracoastal waterway that extends from St. Marks, Florida to Brownsville, Texas. The Sabine-Neches Ship Channel is part of that system with channel depths to safely accommodate large petro-chemical tankers and cargo ships. The Port is 19 miles from the Gulf of Mexico with 24-hour channel and dock accessibility.
