The Tennessee–Tombigbee Waterway is a 234-mile (377 km) artificial U.S. waterway built in the 20th century from the Tennessee River to the junction of the Black Warrior-Tombigbee River system near Demopolis, Alabama. The Tennessee–Tombigbee Waterway links commercial navigation from the nation's midsection to the Gulf of Mexico. The major features of the waterway are 234 miles (377 km) of navigation channels, a 175-foot-deep (53 m) cut between the watersheds of the Tombigbee and Tennessee rivers, and ten locks and dams. The locks are 9 by 110 by 600 feet, the same dimension as those on the Mississippi above Lock and Dam 26 at Alton, Illinois. Under construction for 12 years by the U.S. Army Corps of Engineers, the Tennessee–Tombigbee Waterway was completed in December 1984 at a total cost of nearly $2 billion.
The McAlpine Locks and Dam are a set of locks and a hydroelectric dam at the Falls of the Ohio River at Louisville, Kentucky.

The locks and their associated canal were the first major engineering project on the Ohio River, completed in 1830 as the Louisville and Portland Canal, designed to allow shipping traffic to navigate through the Falls of the Ohio.
The McClellan–Kerr Arkansas River Navigation System (MKARNS) is part of the United States inland waterway system originating at the Tulsa Port of Catoosa and running southeast through Oklahoma and Arkansas to the Mississippi River.
