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 San Francisco, California, to Teaneck, New Jersey, in the New York metropolitan area.

I-355 runs from I-80 in New Lenox north to I-290 in Itasca, a distance of 32.5 miles (52.3 km). With the exception of a four-mile (6.4 km) expansion in 2009, from U.S. Route 34 to 75th Street, the highway is six lanes wide for its entire length.
The Scudder Falls Bridge is a toll bridge that carries Interstate 295 (I-295) over the Delaware River, connecting Lower Makefield Township in Bucks County, Pennsylvania, with the Scudders Falls section of Ewing Township in Mercer County, New Jersey, United States. It is maintained by the Delaware River Joint Toll Bridge Commission (DRJTBC). The original bridge was a plate girder bridge constructed from 1958 to 1961, and the current structure is a box-girder bridge that partially opened in 2019 and was substantially complete in 2021. Previously, the bridge was a toll-free crossing. However, this changed on July 14, 2019, when an all-electronic toll was levied for Pennsylvania-bound traffic; the toll can be paid using E-ZPass or Toll-by-Plate.
Interstate 294 (I-294) is a tolled auxiliary Interstate Highway in the northeastern part of the U.S. state of Illinois.

The Newburgh–Beacon Bridge is a continuous truss toll bridge that spans the Hudson River in New York State. The bridge carries Interstate 84 (I-84) and New York State Route 52 (NY 52) between Newburgh and Beacon and consists of two separate spans. The original northern span, which now carries westbound traffic, was opened on November 2, 1963, as a two-lane bridge. A second span, completed in 1980, now carries all eastbound traffic. The span provides connections to the New York State Thruway (I-87) and U.S. Route 9W (US 9W) in Newburgh and US 9 in Fishkill. The bridges includes a 2,204-foot-long (672 m) cantilever span, with a main span of 1,000 feet (300 m) and side spans of 602 feet (183 m). The total length of all spans and approaches is 7,855 feet (2,394 m) for the north span and 7,789 feet (2,374 m) for the south span. The bridges, owned by the New York State Bridge Authority, carry six lanes of traffic and approximately 65,000 vehicles per day. The bridge is officially known as the Hamilton Fish Newburgh–Beacon Bridge.
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 Columbia River Bridge at Wenatchee, Washington, also known as the Old Wenatchee Bridge and W.T. Clark Pipeline Bridge was built by the Washington Bridge Company in 1908, primarily as a means to carry irrigation water pipelines across the Columbia River. It was the first road bridge over the Columbia south of Canada. The bridge is a pin-connected cantilever truss, 1,600 feet (490 m) long, with one 200-foot (61 m) Pratt truss between two 160-foot (49 m) cantilever arms, with 240-foot (73 m) side arms and a 60 feet (18 m) girder span. The bridge was purchased by the Washington highway department for $182,000 for highway use. As originally built, the bridge carried a 20.5-foot (6.2 m) wide timber roadway, with additional ability to carry a street railway. However, the east approach to the bridge was built at a 6% grade, limiting its potential.
The Evergreen Point Floating Bridge, also known as the 520 Bridge and officially the Governor Albert D.
