U.S. Route 160 (US 160) is a 1,465 mile (2,358 km) long east–west United States highway in the Midwestern and Western United States. The western terminus of the route is at US 89 five miles (8 km) west of Tuba City, Arizona. The eastern terminus is at US 67 and Missouri 158 southwest of Poplar Bluff, Missouri.

U.S. Route 59 is a north–south United States highway. A latecomer to the U.S. numbered route system, US 59 is now a border-to-border route, part of the NAFTA Corridor Highway System. It parallels U.S. Route 75 for nearly its entire route, never much more than 100 miles (160 km) away, until it veers southwest in Houston, Texas. Its number is out of place since US 59 is either concurrent with or entirely west of U.S. Route 71. The highway's northern terminus is 9 mi (14 km) north of Lancaster, Minnesota, at the Lancaster–Tolstoi Border Crossing on the Canada–US border, where it continues as Manitoba Highway 59. Its southern terminus is at the Mexico–US border in Laredo, Texas, where it continues as Mexican Federal Highway 85D.
U.S. Route 71 or U.S. Highway 71 is a major north–south United States highway that extends for over 1500 miles (2500 km) in the central United States. This original 1926 route has remained largely unchanged by encroaching Interstate highways. Currently, the highway's northern terminus is in International Falls, Minnesota at the Canada–US border, at the southern end of the Fort Frances-International Falls International Bridge to Fort Frances, Ontario. U.S. Route 53 also ends here. On the other side of the bridge, Trans-Canada Highway is an east–west route while Highway 71 is a north–south route. US 71's southern terminus is between Port Barre and Krotz Springs, Louisiana at an intersection with U.S. Route 190. For the entirety south of Kansas City, Missouri, US 71 runs parallel and concurrent with the existing and future Interstate 49. North of Kansas City, US 71 runs halfway between Interstate 29 and Interstate 35, which they split in the city at an interchange with Interstate 70.
U.S. Route 166 (US 166) is a 164-mile (264 km) west–east United States highway. This route and US-266 are the only two remaining spurs of historic U.S. Route 66, since US-666 was renumbered to US-491 in 2003.

U.S. Highway 218 is an original United States Highway, created in 1926. Although technically a spur of U.S. Route 18, US 218 neither begins nor ends at US 18, but overlaps US 18 for 8 miles (13 km) near Charles City, Iowa. US 218 begins at U.S. Route 136 in downtown Keokuk and ends 319 miles (513 km) away at Interstate 35 and U.S. Route 14 at Owatonna, Minnesota. A large portion of US 218 in Iowa is part of the Avenue of the Saints, which connects St. Louis, Missouri, and Saint Paul, Minnesota.

New York State Route 70 (NY 70) is a short state highway in the western portion of New York in the United States. It travels through three different counties in just 18.01 miles (28.98 km) and is the primary road to and from the village of Canaseraga. The western terminus of the route is at an intersection with NY 436 in the Livingston County town of Portage. Its eastern terminus is at a junction with NY 36 in the Steuben County town of Dansville. Although NY 70 is mostly signed north–south, it follows a more southeast–northwest alignment and is considered an east–west route by the New York State Department of Transportation (NYSDOT). The portion of the route between Dalton and Canaseraga parallels both Canaseraga Creek and the Norfolk Southern Railway's Southern Tier Line.
Highway 72 is a designation for two east–west state highways in Benton County, Arkansas. A western route of 26.32 miles (42.36 km) runs east from Highway 43 at Maysville to U.S. Route 71B (US 71B) in Bentonville. A second route of 12.67 miles (20.39 km) begins at Interstate 49/US Route 71 (I-49/US 71) in Bentonville and runs northeast to US 62 near Avoca.
