The Gulf Intracoastal Waterway (GIWW) is the portion of the Intracoastal Waterway located along the Gulf Coast of the United States. It is a navigable inland waterway running approximately 1,300 mi (2,100 km) from St. Marks, Florida, to Brownsville, Texas. The waterway provides a channel with a controlling depth of 12 ft (3.7 m), designed primarily for barge transportation.
