The Illinois and Michigan Canal connected the Great Lakes to the Mississippi River and the Gulf of Mexico. In Illinois, it ran 96 miles (154 km) from the Chicago River in Bridgeport, Chicago to the Illinois River at LaSalle-Peru. The canal crossed the Chicago Portage, and helped establish Chicago as the transportation hub of the United States, before the railroad era. It was opened in 1848. Its function was largely replaced by the wider and shorter Chicago Sanitary and Ship Canal in 1900, and it ceased transportation operations with the completion of the Illinois Waterway in 1933.
The Chesapeake and Ohio Canal, abbreviated as the C&O Canal and occasionally called the "Grand Old Ditch," operated from 1831 until 1924 along the Potomac River from Washington, D.C., to Cumberland, Maryland. The canal's principal cargo was coal from the Allegheny Mountains.
The Hertford Union Canal or Duckett's Cut is just over 1 mile (1.6 km) long in the London Borough of Tower Hamlets in East London. It connects the Regent's Canal to the Lee Navigation.

The Chesapeake and Ohio Canal National Historical Park is located in the District of Columbia and the states of Maryland and West Virginia. The park was established in 1961 as a National Monument by President Dwight D. Eisenhower to preserve the neglected remains of the Chesapeake and Ohio Canal and many of its original structures. The canal and towpath trail extends along the Potomac River from Georgetown, Washington, D.C., to Cumberland, Maryland, a distance of 184.5 miles (296.9 km). In 2013, the path was designated as the first section of U.S. Bicycle Route 50.

Lock and Dam No. 14 is a lock and dam located near LeClaire, Iowa on the Upper Mississippi River above Davenport, Iowa and Moline, Illinois. The movable portion of the dam is 1,343 feet (409.3 m) long and consists of 13 tainter gates and 4 roller gates. Connected to it is a 1,127 feet (343.5 m) long non-submersible rock fill dike which extends to the Illinois side. The main lock is 110 feet (33.5 m) wide by 600 feet (182.9 m) long. The site on the National Register of Historic Places as the Lock and Dam No. 14 Historic District (#04000174) listed in 2004 consisting of 3,043 acres (12.3 km2), 1 building, 6 structures, and 2 objects. It was completed in two phases, the first as part of the six foot channel project from 1921 to 1924, which included a lock and canal bypassing a hazardous rapids. The second phase was part of the nine foot channel project from 1935 to 1939 and included the main dam and the current main lock.
Lock and Dam No. 15 is a lock and dam located on the Upper Mississippi River. It spans the river between Rock Island, Illinois and Davenport, Iowa.

It is unusual among the upper Mississippi River dams in that it has only roller gates, has different sizes and types of roller gates, it is not perpendicular to the flow of the river and is one of the few facilities that has a completed auxiliary lock. The main lock is 110 feet (33.5 m) wide by 600 feet (180 m) long and its auxiliary lock is 110 feet (34 m) wide by 360 feet (110 m) long.

The Lehigh Canal or the Lehigh Navigation Canal is a navigable canal, beginning at the mouth of Nesquehoning Creek on the Lehigh River in Eastern Pennsylvania. It was built in two sections over a span of twenty years, beginning in 1818. The lower section spanned the distance between Easton, Pennsylvania and the town of Mauch Chunk, present-day Jim Thorpe, Pennsylvania. In Easton the canal met the Delaware and Morris Canals, with which goods could be brought further up the east coast. At its height, the Lehigh Canal was 72 miles (116 km) long.

The Georges River Canal, also known as the General Knox Canal was a short-lived canal that operated on and near the course of the Saint George River in Knox and Waldo Counties in south-central Maine. First owned and operated by American Revolutionary War General Henry Knox between 1794 and 1806, it was briefly revived in 1847-50, but was not financially successful. It provided for transport of goods from near the river's headwaters in Searsmont to the head of navigation at Warren. A few elements of the canal survive today, and its route was listed on the National Register of Historic Places in 1970.
