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.
Interstate 80 (I-80) is an east–west transcontinental freeway that crosses the United States from downtown San Francisco, California, to Teaneck, New Jersey, in the New York metropolitan area.

The second-longest Interstate Highway in the United States after I-90, it runs through many major cities, including Oakland, Sacramento, Reno, Salt Lake City, Omaha, Des Moines, and Toledo and passes within 10 miles (16 km) of Chicago, Cleveland, and New York City.
Interstate 90 (I-90) is an east–west transcontinental freeway and the longest Interstate Highway in the United States at 3,021 miles (4,862 km).

The old Chain of Rocks Bridge spans the Mississippi River on the north edge of St. Louis, Missouri, United States. The eastern end of the bridge is on Chouteau Island, while the western end is on the Missouri shoreline. Its most notable feature is a 22-degree bend occurring at the middle of the crossing, which was found to be necessary during construction due to both the presence of a water intake and the inability of parts of the bedrock of the river to carry the weight of the bridge.
An Illinois Tollway oasis is a type of commercialized rest area sited over Interstate Highways that are part of the Illinois Tollway system in northern Illinois, United States. The four oases offer food and gasoline vendors and are found in the Chicago Metropolitan Area, DeKalb, and Belvidere. Although the oases date back to the original tollway construction in 1958, they were redeveloped in 2003–2005 by Wilton Partners, a private developer. The redevelopment of the oases has been the focal point of alleged political corruption. The four oases are administered by a court-appointed manager following default of Wilton Partners.
The Arthur Ravenel Jr. Bridge is a cable-stayed bridge over the Cooper River in South Carolina, US, connecting downtown Charleston to Mount Pleasant.

The McKinley Bridge is a steel truss bridge across the Mississippi River. It connects northern portions of the city of St. Louis, Missouri with Venice, Illinois. It opened in 1910 and was taken out of service on October 30, 2001. The bridge was reopened for pedestrian and bicyclists on November 17, 2007 with a grand re-opening celebration.
