U.S. Route 371 is a north–south United States highway in the U.S. states of Arkansas and Louisiana. The highway's northern terminus is in De Queen, Arkansas at an intersection with U.S. Highway 70. It is co-signed for its last 13 miles (21 km) between Lockesburg, Arkansas and DeQueen with U.S. Highway 59 and U.S. Highway 71. Its southern terminus is 5 miles (8.0 km) west of Coushatta, Louisiana at an intersection with Interstate 49.

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.
