Interstate 45 (I-45) is a major Interstate Highway located entirely within the U.S. state of Texas. While most Interstate routes which have numbers ending in "5" are cross-country north–south routes, I-45 is comparatively short, with the entire route located in Texas. Additionally, it has the shortest length of all the interstates that end in a "5". It connects the cities of Dallas and Houston, continuing southeast from Houston to Galveston over the Galveston Causeway to the Gulf of Mexico.
Interstate 355 (I-355), also known as the Veterans Memorial Tollway, is an Interstate Highway and tollway in the western and southwest suburbs of Chicago in the U.S. state of Illinois.

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.

State Highway 360 is a 28-mile (45 km) north–south state highway in the Dallas–Fort Worth metroplex in the U.S. state of Texas. It runs north from an at-grade intersection with US 287 in Mansfield, near the Ellis-Johnson county line to a partial interchange with SH 121 in Grapevine, near Dallas/Fort Worth International Airport. The highway serves as a local north–south route running through the center of the metroplex, linking together the southern and northern suburbs to the core. Between US 287 and Camp Wisdom Road/Sublett Road, SH 360 follows a pair of frontage roads along a four-lane tollway known as the 360 Tollway, a tollway operated by the NTTA. Between Camp Wisdom Road/Sublett Road and SH 121, SH 360 follows a toll-free freeway maintained by TxDOT.
Interstate 88 (I-88) is an Interstate Highway in the US state of Illinois that runs from an interchange with I-80 near Silvis and Moline to an interchange with I-290 and I-294 in Hillside, near Chicago.

The highway also runs through the cities of Aurora, Naperville, DeKalb, and Dixon. East of Rock Falls, the route is a part of the Illinois Tollway system.
The President George Bush Turnpike (PGBT) is a 52-mile (84 km) toll road running through the northern, northeastern and western suburbs, forming a partial loop around Dallas, Texas, United States. It is named for the late George H. W. Bush, the 41st president of the United States. At its west end near Belt Line Road in Irving, State Highway 161 continues southwest to Interstate 20 (I-20) in Grand Prairie. The discontinuous free frontage roads along the turnpike from I-35E in Carrollton east to its end at I-30 in Garland are assigned the State Highway 190 designation. SH 190 signage appears only along the Rowlett, Garland, Richardson, Plano, and Carrollton sections of the frontage road with the undersign "frontage road only". At intersections with city streets, only the Bush Turnpike signs are displayed, not the SH 190 signage. Prior to the construction of the main lanes as a tollway, SH 190 was used as the name of the planned main lanes too. Similarly, the part west of I-35E was planned as part of SH 161. Bush Turnpike is signed as a north–south road from I-20 to I-35E, an east–west road from I-35E to the Merritt Main Lane Gantry and as a north–south road from the Merritt Main Lane Gantry to I-30, as Bush Turnpike makes a nearly 90-degree curve in both places.
The Dallas North Tollway is a 30.2-mile (49 km) controlled-access toll road operated by the North Texas Tollway Authority (NTTA), which runs from Interstate 35E near downtown Dallas, Texas (USA), to U.S. Highway 380, in Frisco, Texas.
Interstate 635 (I-635) is a 37-mile-long (60 km) partial loop around Dallas, Texas, in the United States between I-20 in Balch Springs and State Highway 121 (SH 121) at the north entrance of the Dallas/Fort Worth International Airport (DFW Airport) in Grapevine. It intersects I-35E at exits 27B and 27C, but does not connect with I-35W. I-635 and a part of I-20 are collectively designated as the Lyndon B. Johnson Freeway; known locally as the LBJ Freeway, or simply LBJ. The roadway is named after Lyndon B. Johnson, the former US Senator from Texas, 37th Vice President, and the 36th President of the United States. Where I-635 ends at I-20, I-20 continues the LBJ Freeway designation heading west. Since the portion of I-20 between State Highway Spur 408 (Spur 408) to I-635 retains the same names as I-635, the two highways are considered 3/4 of the beltway around Dallas. Together with Spur 408, a portion of State Highway Loop 12, and a portion of I-35E, the Stemmons Freeway, I-635 and I-20 complete the beltway.

Interstate 90 (I-90) in the US state of Illinois runs roughly northwest-to-southeast through the northern part of the state. From the Wisconsin state line at South Beloit, it heads south to Rockford before heading east-southeast to the Indiana state line at Chicago.

A barrier toll system is a method of collecting tolls on highways using toll barriers at regularly spaced intervals on the toll road's mainline. Motorists are typically charged a flat-rate toll, unlike toll roads with a ticket system where the toll rate is determined by the distance traveled or number of exits passed. Some highways use coin-drop machines on toll plazas. For toll roads whose ramps have no toll plazas, it is possible to exit the toll road before the mainline toll plaza, use local streets to bypass it, then re-enter the highway via an interchange on the other side of the toll plaza. Thus it is possible to drive on some barrier toll roads while paying less or not paying at all; this is the basis of the "open" descriptor.
There are approximately 25 current toll roads in the state of Texas. Toll roads are more common in Texas than in many other U.S. states, since the relatively low revenues from the state's gasoline tax limits highway planners' means to fund the construction and operation of highways.
The Sam Rayburn Tollway is a tollway operated by the North Texas Tollway Authority that runs from Grapevine to McKinney. Its frontage roads are signed State Highway 121.
