The Gulf Intracoastal Waterway
Intracoastal Waterway
is the portion of the Intracoastal Waterway located along the Gulf Coast of the United States. It is a navigable inland waterway running approximately 1,050 mi (1,690 km) from Carrabelle, Florida, to Brownsville, Texas. The waterway provides a channel with a controlling depth of 12 ft (3.7 m), designed primarily for barge transportation. Although the U.S. government proposals for such a waterway were made in the early 19th century,[1] the Gulf Intracoastal Waterway

was not completed until 1949.[2]
