Intracoastal Waterway

The Intracoastal Waterway is a network of navigable routes along the Atlantic and Gulf coasts of the United States. It links ports through protected rivers, bays, sounds, canals, and other inland waters.

Atlantic Intracoastal Waterway: The coastal waterway route running from Norfolk, Virginia, to the Florida Keys. This section carries the network along the Atlantic coast.
Rivers and Harbors Act of 1899: A United States law governing construction in navigable waters and protecting federal navigation projects. Federal control of navigable waters shaped how the waterway could be developed.
Barge: A flat-bottomed vessel used to carry cargo on rivers and canals. Barges move bulk goods along the waterway's shallow, sheltered channels.
Gulf Coast: The coastal region bordering the Gulf of Mexico in the United States. The waterway links communities and industries across this broad coastal region.
Gulf Intracoastal Waterway: A protected inland navigation route along the Gulf Coast from Florida to Texas. It forms the network's long Gulf Coast section.
Federal Highway Act of 1956: A United States law that funded the Interstate Highway System. Highway expansion offered a competing national transportation investment during the waterway's modern development.
Towboat: A powerful vessel designed to push or pull barges on inland waterways. Towboats make long freight tows practical on the Gulf route.
Coastal erosion: The wearing away of shorelines by waves, currents, storms, and other forces. Dredging and navigation infrastructure can alter sediment movement near the route.
Atlantic Intracoastal Waterway (Virginia–Florida): The Atlantic route connecting Virginia with Florida through coastal waters and canals. This stretch shows how connected coastal waterways form a continuous route.
Intracoastal Waterway (Louisiana): The Louisiana section of the Gulf Intracoastal Waterway, connecting coastal ports and waterways. Its development illustrates the Gulf route's dependence on engineered channels.
