U.S. Route 71
U.S. Route 71 (US 71) is a major north–south United States Numbered Highway spanning 1,532 miles (2,465 km) through the central United States, with its southern terminus at an intersection with US 190 west of Krotz Springs, Louisiana, and its northern terminus at the Canada–United States border in International Falls, Minnesota.[1] The highway traverses six states: Louisiana, a brief portion of Texas near Texarkana, Arkansas, Missouri, Iowa, and Minnesota, serving as a vital transportation corridor connecting rural areas, major cities, and trade routes in the region.[1] In Louisiana, US 71 covers approximately 231 miles, passing through Shreveport and paralleling portions of Interstate 49 (I-49), which it joins in several segments. Upon entering Texas for about 3 miles in Texarkana, it quickly crosses into Arkansas, where it extends roughly 300 miles through nine counties, linking Texarkana, Fort Smith, and Fayetteville while overlapping with US 59, US 270, and segments of I-40, I-49, and I-540.[1] Continuing northward, US 71 enters Missouri for about 317 miles, traversing the Ozarks near Joplin and serving as a key artery through Kansas City before heading into northwest Missouri.[2] In Iowa, the route measures 232 miles, connecting rural communities and passing through Sioux City en route to the Minnesota border.[3] Finally, in Minnesota, US 71 spans 399 miles across the northern part of the state, going through Bemidji and providing access to lakes and forests before reaching International Falls.[4] Established in 1926 as part of the original U.S. Highway System, US 71 has evolved from two-lane rural roads to include modern divided highways, facilitating commerce, tourism, and connectivity along its path.[1]Route information
Length and establishment
U.S. Route 71 spans a total length of 1,532 miles (2,466 km) as of 2025.[1] This distance is distributed across six states, with approximately 231 miles in Louisiana, 3 miles in Texas, 298 miles in Arkansas, 317 miles in Missouri, 231 miles in Iowa, and 399 miles in Minnesota.[5][6][7][3][4] The route was established in 1926 as part of the initial U.S. Highway System, created by the Joint Board on Interstate Highways under the Bureau of Public Roads.[8] Its original southern terminus was in Port Allen, Louisiana, near Baton Rouge, while the northern terminus was at International Falls, Minnesota, connecting to the Canadian border.[8][2] As an odd-numbered highway, U.S. Route 71 follows the conventions of the U.S. Numbered Highway System, designating it as a primary north-south route that links the Gulf Coast region to the northern border areas.[9] Portions of the route overlap with Interstate 49 in Louisiana, Arkansas, and Missouri.Major cities and features
U.S. Route 71 passes through several notable urban centers across its path in six states. In Louisiana, the highway begins near the small community of Krotz Springs and serves the city of Alexandria before heading northwest toward the state line.[5] At the Texas-Arkansas border, it bisects the twin cities of Texarkana, a key regional hub. In Arkansas, the route traverses Fort Smith, a major port city on the Arkansas River, and continues to Fayetteville, home to the University of Arkansas.[1] Further north in Missouri, US 71 connects Joplin, an industrial center, and Kansas City, a major metropolitan area and transportation nexus, while running parallel to the western fringes of the Springfield metropolitan region. In Iowa, it links communities like Spencer amid agricultural landscapes. The highway culminates in Minnesota, passing through Bemidji before reaching its northern terminus at International Falls near the Canadian border.[10][11] The route features diverse natural landscapes that highlight its progression from southern woodlands to northern prairies. In Arkansas and Missouri, US 71 parallels the western edge of the Ozark Mountains, traversing rugged terrain through the Boston Mountains and offering scenic views of forested hills and valleys.[12] Further north, it crosses the Mississippi River just southwest of Bemidji, Minnesota, via a modern divided bridge completed in 1979. In its northern reaches, the highway provides access to Voyageurs National Park, with International Falls serving as the primary southern gateway to this aquatic wilderness area spanning lakes and boreal forests.[13][14] Southern segments wind through rural forested regions, while northern portions cut across expansive agricultural plains dedicated to corn and soybean production.[1] Economically, US 71 functions as a vital freight corridor, facilitating the transport of goods from Gulf Coast ports in Louisiana to manufacturing and distribution hubs in the Midwest, particularly Kansas City.[15] Portions of the route overlap with Interstate 49, enhancing its capacity for heavy truck traffic and commercial logistics across the region. The highway spans Louisiana, a brief segment in Texas, Arkansas, Missouri, Iowa, and Minnesota, terminating at the international crossing to Fort Frances, Ontario, Canada.[16][1]Route description
Louisiana
U.S. Route 71 begins in Louisiana at its southern terminus, a junction with U.S. Route 190 in Krotz Springs in St. Landry Parish.[5] The highway heads northwest from there, traversing rural landscapes marked by bayou crossings in the southern portion of the state, including passages over waterways in the Atchafalaya Basin region.[17] As it progresses, US 71 enters Avoyelles and Rapides Parishes, serving as a key connector through central Louisiana's agricultural and forested areas. In Rapides Parish, the route passes through Alexandria, a regional hub and the largest city along its path in the state, which features England Air Park, a former U.S. Air Force base converted into a multi-modal commerce center and airport supporting economic development.[18] North of Alexandria, US 71 continues into Grant, Winn, and Natchitoches Parishes, crossing pine forests and rural terrain before reaching Natchitoches, noted for its historical significance as the oldest permanent settlement in the Louisiana Purchase territory and home to Creole heritage sites along the Cane River, including preserved plantations and cultural landmarks.[19] The highway here remains predominantly four-laned, facilitating efficient travel through these communities.[5] Further north, US 71 enters Red River and DeSoto Parishes en route to Caddo Parish and Shreveport, a major port city situated on the west bank of the Red River, which serves as an inland navigation hub for cargo transport.[20] In the Shreveport–Bossier City metropolitan area, the route overlaps briefly with Interstate 20 through Bossier City and into Shreveport, providing access to urban centers and crossing the Red River via the Texas Street Bridge.[21] It also intersects Interstate 220, the local bypass loop. Throughout Louisiana, US 71 is largely four-laned and closely paralleled by Interstate 49, with portions designated as future I-49 segments to enhance connectivity along the corridor.[5] From Shreveport, the highway veers northwest through suburban and rural expanses of Caddo Parish, characterized by pine woodlands and occasional bayou features, before reaching the Texas state line near the community of Rodessa after spanning 231.10 miles in the state.[5]Arkansas and Texas
U.S. Route 71 enters Texas from Louisiana in Bowie County near Rodessa, traveling approximately 3 miles (2.942 miles per TxDOT) northeast through rural areas to the twin city of Texarkana, which straddles the Texas-Arkansas state line.[6] In Texarkana, the route overlaps with U.S. Route 82 along Richmond Road and State Line Avenue, forming the dividing line between the Texas and Arkansas portions of the city, and intersects Interstate 30 near the central business district.[22][23] This brief Texas segment serves primarily as a connector in the northeastern corner of the state, facilitating cross-border traffic in the bifurcated urban area.[22] Crossing the Red River into Arkansas south of Kiblah in Miller County, U.S. Route 71 extends northward for about 300 miles across nine counties, passing through a mix of rural landscapes and growing urban centers.[1] The highway initially traverses flat to gently rolling terrain near Texarkana, where it concurs briefly with U.S. Routes 67 and 82, before heading to Ashdown and then De Queen in Sevier County.[1] Near De Queen, it overlaps with U.S. Route 70, providing access to local agriculture and timber industries.[1] Continuing north, the route enters the Ouachita Mountains, characterized by hilly, forested terrain within the Ouachita National Forest, and passes through Mena in Polk County, a gateway to recreational areas including hiking trails and the nearby Talimena Scenic Drive.[1] Here, U.S. 71 joins U.S. Route 270 west of Y City, overlapping for several miles through the rugged landscape and crossing the Ouachita River before splitting off near Mount Ida.[1] The highway's path winds through steep grades and curves, reflecting its origins along historic Native American and stagecoach trails.[1] Further north, U.S. 71 reaches the Arkansas River Valley, crossing the river at Fort Smith in Sebastian County via the Interstate 540 bridge, and intersects Interstate 40 on the city's north side.[1] Construction on a new I-49 bridge over the Arkansas River began in August 2025, which will include US 71 in its alignment as part of the I-49 extension (as of November 2025).[24] It then proceeds through Van Buren and Alma before ascending into the Boston Mountains, part of the Ozark Plateau, where the terrain shifts to more elevated plateaus with flatter stretches amid dense forests in the Ozark National Forest.[1] The route serves the growing Northwest Arkansas region, passing Fayetteville in Washington County—home to the University of Arkansas—and overlapping with the future alignment of Interstate 49 toward Springdale, Rogers, and Bentonville in Benton County, the latter known as the headquarters of Walmart.[1] Near the Missouri state line north of Bella Vista, the highway transitions to less rugged, more developed suburban areas, completing its Arkansas traversal.[1]Missouri
U.S. Route 71 enters Missouri from Arkansas near the town of Jane in McDonald County, immediately signed concurrently with Interstate 49 northward through the rugged terrain of the Ozark Mountains. The highway passes through small communities such as Pineville and Anderson before reaching Joplin in Jasper County, a historic center for lead and zinc mining that produced much of the nation's output from the late 19th to mid-20th centuries. In Joplin, US 71 intersects Interstate 44 and continues north as a four-lane freeway, serving industrial areas tied to the region's mining legacy.[10][25] North of Joplin, the route proceeds through the western Ozarks via Carthage in Jasper County and Lamar in Barton County, transitioning from hilly landscapes to rolling prairies as it enters Bates and Cass counties en route to Harrisonville. Approaching the Kansas City metropolitan area, US 71 remains a divided freeway, overlapping I-49 to its terminus at I-435 and I-470 on the city's southeast side; from there, US 71 briefly overlaps I-70 before joining I-29 northwest through urban Kansas City and onward to St. Joseph in Buchanan County, where the concurrency with I-29 ends. This segment functions as a vital commuter corridor for the Kansas City metro, facilitating daily travel between suburbs like Belton and downtown while supporting logistics along the I-49 freight pathway.[10][16][26][27] Beyond St. Joseph, US 71 travels through rural northwest Missouri farmlands in Andrew, Holt, and Nodaway counties, passing near Savannah and reaching Maryville before crossing into Iowa near the town of Clearmont. The entire Missouri segment spans approximately 317 miles, designated as future Interstate 49 under the 1991 Intermodal Surface Transportation Efficiency Act to enhance connectivity from the Ozarks to the northern border. By the early 2000s, most of the route had been upgraded to four lanes, with the exception of the northernmost segment from Maryville to the Iowa state line, which remains two-lane, improving safety and capacity across much of its diverse terrain from southern highlands to northern plains.[10][28][29]Iowa
U.S. Route 71 enters Iowa from Missouri at Braddyville in Page County, marking the beginning of its 231-mile journey through the western part of the state. The highway initially passes through rural farmland in Page County, serving the county seat of Clarinda, a small city in the Loess Hills region known for its agricultural heritage. From there, it continues northward into Montgomery County before entering Cass County, where it intersects Interstate 80 (I-80) just south of Atlantic via a brief overlap with U.S. Route 6 (US 6). This section traverses the farm belt of southwestern Iowa, characterized by expansive cornfields and livestock operations that dominate the local economy.[3][11] Proceeding north, US 71 enters Audubon County, passing through the county seat of Audubon, before reaching Carroll County and the city of Carroll, where it intersects U.S. Route 30 (US 30). The route then shifts into Sac County, intersecting U.S. Route 20 (US 20) near Sioux Rapids in Buena Vista County after a short overlap with US 20 through portions of Sac County. Throughout this central segment, the highway winds through rolling plains dedicated primarily to grain and livestock production, with two-lane undivided sections facilitating local traffic in these agricultural communities.[3][11] In Buena Vista County, US 71 follows a four-lane bypass east of Storm Lake, completed in November 1996 to improve traffic flow around the lakeside community and straighten the alignment. This upgrade replaced the former routing that entered Storm Lake concurrently with Iowa Highway 7 (IA 7). North of the bypass, the highway enters Clay County, passing through Spencer, the county seat and a regional hub for farming and manufacturing. Beyond Spencer, US 71 continues through Dickinson County, serving Spirit Lake near the northern state line, amid a landscape of prairie grasslands transitioning to the Iowa Great Lakes region. The route remains predominantly two- to four-laned, emphasizing connectivity for rural economies centered on corn, soybeans, and dairy production. It exits Iowa at the Minnesota border south of Jackson, Minnesota, after spanning predominantly flat to gently rolling terrain that supports Iowa's vital agricultural sector.[3][11][30]Minnesota
U.S. Route 71 enters Minnesota from Iowa at the state line south of Jackson in Jackson County. The highway then passes through the city of Jackson in Jackson County, where it intersects Interstate 90 (I-90). Continuing northward, it traverses rural areas, passing through Windom in Cottonwood County before reaching Willmar in Kandiyohi County, where it overlaps with U.S. Route 12 (US 12) through the city.[31][32] From Willmar, US 71 proceeds to Sauk Centre in Stearns County and then to Wadena in Wadena County. The route continues north through Hubbard County to Bemidji in Beltrami County, near the headwaters of the Mississippi River at Lake Itasca. Near Bemidji, it briefly intersects U.S. Route 2 (US 2). Further north, the highway passes through forested areas in Itasca and Koochiching counties before arriving at International Falls.[31][32] Spanning approximately 399 miles (642 km) across southern and northern Minnesota, US 71 is predominantly a two-lane rural highway that winds through the state's north woods, characterized by numerous lakes, peatlands, and boreal forests. It serves as a key corridor for tourism, providing access to remote wilderness areas including the Boundary Waters Canoe Area Wilderness via connections near International Falls. The route terminates at the Canada–United States border in International Falls, crossing the Rainy River via the International Bridge to Fort Frances, Ontario.[4][31]History
Establishment in 1926
U.S. Route 71 was formed in November 1926 by the Joint Board on Interstate Highways, a federal-state panel that served as the predecessor to the American Association of State Highway Officials (AASHO), as one of approximately 75 original U.S. Routes designed to create a standardized network for long-distance interstate travel.[9] The route's odd numbering adhered to the system's convention for north-south highways, facilitating logical navigation across the nation.[9] The original alignment started at a junction with U.S. Route 61 in Port Allen, Louisiana—directly across the Mississippi River ferry from Baton Rouge—and proceeded northward approximately 1,500 miles through key cities including Shreveport, Louisiana; Texarkana on the Texas-Arkansas border; Fort Smith and Fayetteville, Arkansas; Springfield and Kansas City, Missouri; Sioux City, Iowa; and terminated at International Falls, Minnesota, adjacent to the Canadian border.[2][1] This path largely supplanted existing state-marked roads in central Louisiana, integrating fragmented local routes into a cohesive national corridor.[33] The highway's initial purpose was to link southern Mississippi River ports, like Baton Rouge, with northern trade routes extending toward Canadian markets, promoting commerce and mobility in the central United States.[9] At establishment, most segments consisted of gravel or unpaved dirt surfaces, typical of the era's rudimentary infrastructure, with improvements driven by local road districts before widespread federal paving efforts in the 1930s.[33][1]Post-1926 developments
During the 1930s, the Arkansas State Highway Department, supported by federal New Deal funding, paved several sections of US 71 through the Ozarks, including alignments near West Fork and Devil's Den State Park, to provide all-weather access in the mountainous region.[34] In 1941, the southern terminus was relocated south to Baton Rouge, Louisiana, and in 1951, it was further adjusted to its current location at an intersection with Louisiana Highway 10 west of Krotz Springs.[2] In the 1970s, Missouri began upgrading US 71 to four lanes from Joplin to Kansas City, starting south of Nevada and completing phased widenings to enhance freight and commuter capacity along the northern corridor.[28] The 1991 Intermodal Surface Transportation Efficiency Act (ISTEA) identified southern segments of US 71 as a high-priority corridor for Interstate 49, prompting comprehensive realignments and widenings; this led to Missouri's full four-lane upgrade of the route by 2012.[35][28] These developments often involved brief overlaps with emerging interstates to improve connectivity.Future developments
I-49 designation and upgrades
In 1991, the Intermodal Surface Transportation Efficiency Act (ISTEA) designated segments of U.S. Route 71 as future Interstate 49 (I-49) from Shreveport, Louisiana, northward to Kansas City, Missouri, establishing a high-priority corridor to develop a continuous north-south interstate link connecting New Orleans, Louisiana, to Kansas City.[29][36] Upgrades to achieve interstate standards along these segments encompassed the construction of full-access interchanges, elimination of at-grade intersections, provision of 10-foot outside shoulders and 4-foot inside shoulders, and establishment of a 70 mph speed limit in rural areas.[37][38] In Missouri, the approximately 180-mile portion of U.S. 71 was fully upgraded to these standards and officially designated as I-49 on December 12, 2012, with signage reflecting the I-49/U.S. 71 concurrency from the Arkansas state line near Pineville to Kansas City.[16][39] Several gaps remain in the I-49 corridor along U.S. 71, with the largest unbuilt section spanning about 140 miles between Fort Smith, Arkansas, and Texarkana on the Arkansas-Texas border.[40] This gap has been prioritized for completion to support economic development in the Four State Region, facilitating improved freight movement, tourism, and commerce across Arkansas, Missouri, Oklahoma, and Texas.[41][40]Recent and planned projects
On August 22, 2025, the Arkansas Department of Transportation (ARDOT) broke ground on the Interstate 49 (I-49) Arkansas River bridge project near Fort Smith, marking the start of construction for a 3.1-mile segment from Arkansas Highway 22 to Gun Club Road in Sebastian County.[42] This $282.5 million initiative, funded through federal and state sources, aims to link the southern and northern segments of the I-49 corridor across the river, enhancing freight and traveler connectivity in western Arkansas with an expected completion in early 2029.[42] In September 2025, ARDOT initiated preliminary engineering and survey work for a proposed I-49 segment from Barling in Sebastian County to Y City in Scott County, spanning approximately 50 miles as part of a larger environmental study.[43] Budgeted at $3 million to $5 million, the surveys—including terrain mapping and utility location using drones—will conclude by the end of 2026 to support environmental assessments and design plans for a four-lane controlled-access highway.[40][43] The broader I-49 extension from Highway 22 to Interstate 40 in Arkansas, a 14-mile four-phase effort estimated at $1.3 billion, entered construction in 2025 with the river bridge as its initial component, advancing the corridor's role in regional north-south travel.[42] In Louisiana, the I-49 Inner City Connection project in Shreveport remains in the planning phase, focusing on a 3.6-mile urban link to connect existing I-49 segments through the city while undergoing environmental and cultural reviews. As of October 2025, a decision on the preferred route among multiple alternatives is expected soon.[44][45] Initial cost estimates for the project range from $547 million to $640 million, though recent assessments indicate potential increases exceeding $900 million due to inflation and scope adjustments.[46][47] In Missouri, the Kansas City region's 2026–2030 Transportation Improvement Program schedules several upgrades along U.S. Route 71 (concurrent with I-49 in parts) in Cass and Jackson Counties to improve traffic flow and safety.[48] Key efforts include bridge rehabilitation on U.S. 71 over Bannister Road in Jackson County, with construction letting in winter 2025 and completion by spring 2027; pavement reconstruction on I-49 from Blue Ridge Boulevard to south of 155th Street in Cass County, programmed for 2026–2030; and interchange enhancements at U.S. 71 and Missouri Route 150 in Jackson County, set for construction in 2026 at a cost of $15 million.[49][48][48]Major intersections
