The Intracoastal Waterway System is a network of navigable waterways along the Atlantic and Gulf coasts of the United States. It provides a safe route for boats and ships, allowing them to travel without navigating the open ocean. The system includes rivers, bays, and canals, making it essential for commercial and recreational boating. Constructed in the early 20th century, the waterway spans over 3,000 miles and connects various ports and cities. It plays a vital role in trade and transportation, supporting industries and tourism. The system is maintained by the U.S. Army Corps of Engineers and is crucial for regional economies.
