The Tombigbee Waterway is a significant inland waterway in the southeastern United States, connecting the Tombigbee River in Mississippi to the Black Warrior River in Alabama. This 234-mile-long waterway facilitates navigation and transportation, allowing boats and barges to move goods efficiently between the Gulf of Mexico and the interior regions. Constructed in the 20th century, the waterway includes a series of locks and dams that help manage water levels and improve navigation. It plays a crucial role in regional commerce, supporting industries such as agriculture and manufacturing by providing a reliable route for shipping products.
