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 partially replaced by the wider and deeper Chicago Sanitary and Ship Canal in 1900, and it ceased transportation operations with the completion of the Illinois Waterway in 1933.

Walter Mickle Smith, Sr. was a civil engineer who worked primarily on U.S. dams and waterway projects. He was a consulting engineer on the construction of the Panama Canal and Panama Canal Locks and later served as design engineer for the New York Board of Water Supply. He spent much of his career with the State of Illinois waterways division and was its chief engineer until his retirement in 1937. Several of his works built in the 1920s and 1930s as part of the Illinois Waterway project are listed on the National Register of Historic Places, including portions of the Brandon Road Lock and Dam, the Dresden Island Lock and Dam, the Lockport Lock and Power House, and the Marseilles Lock and Dam.
The Dresden Island Lock and Dam is a 23.4-acre (9.5 ha) Lock and Dam complex on the Illinois River in Morris, Illinois. The dam was completed in 1933 and designed by engineer Walter Mickle Smith. It was listed on the National Register of Historic Places in 2004. The listing included one contributing building and three contributing structures.
The Marseilles Lock and Dam, also known as Lock and Dam 5, is a lock and dam complex on the Illinois River at Marseilles, Illinois. The complex includes a lock, dam, control station, boiler house, and a 2.5 miles (4.0 km) section of navigation canal. The state of Illinois began work on the complex in 1920 by digging the canal, which was completed in 1925. The state also began construction on the lock, dam, and control station; however, due to financial difficulties these projects were finished by the U.S. Army Corps of Engineers. Walter Mickle Smith was chief design engineer for the complex. The complex was completed in 1933. The lock has a drop of 24 feet.
LaGrange Lock and Dam is a lock and dam complex on the Illinois River at Versailles, Illinois. The structure includes a 1,066 feet (325 m) dam and a 110 by 600 feet lock. The U.S. Army Corps of Engineers built the complex from 1936 to 1939; A.F. Griffin designed the lock and dam, while Paul Le Gromwell designed the control station. The lock and dam, as well as a similar lock and dam near Peoria, were needed when the authorized channel depth was raised to nine foot. The Peoria and LaGrange locks replaced older locks on the lower Illinois River. The lock uses Chanoine wicket gates, which allow for navigation on the river, rather than the Tainter gates seen elsewhere on the river.
The Peoria Lock and Dam is a historic lock and dam complex on the Illinois River at Creve Coeur, Illinois. The complex was built in 1938-39 as part of an effort to make the river navigable and establish a route for barges between Chicago and the Mississippi River. The U.S. Army Corps of Engineers designed the complex; their influence is particularly evident in the dam's control station, as the State of Illinois designed most other dam control stations along the river. The lock has a standard 100-by-600-foot chamber, similar to other locks on the river, and a vertical lift of 11 feet (3.4 m). The dam is 536 feet (163 m) long and includes 108 wicket gates and a Tainter gate; it is one of two Illinois dams that still use wicket gates. The control station is for the most part a large, functional building, though it has Art Deco surrounds at the main entrance. The district also contains an original maneuver boat designed to raise and lower the dam's wicket gates; the boat is still used and is one of four boats of its kind left in the United States.
