Interstate 540 (I-540) is a freeway spur route of I-40 in the US state of Arkansas in Fort Smith. The total length is 14.71 miles (23.67 km). [1] At first, I-540 was a short spur connecting Fort Smith and Van Buren to I-40 as one of the original five Arkansas Interstates. [2] The route ran just over 14 miles (23 km) to US 271 near the Oklahoma state line. [3] The growing Northwest Arkansas area and the University of Arkansas needed an Interstate connection to Little Rock, and through traffic north to Kansas City had also outgrown the winding US 71 north from I-40. The route was extended north to Mountainburg in the late 1990s on an all-new alignment (going under concurrency with I-40, one of the only auxiliary routes with a concurrency with its parent) with the route being completed to Bella Vista in January 1999. [4] However, the segment north of I-40 became a part of Interstate 49 in 2014.


Route description

The older portion of I-540, completed in the 1970s, connects Interstate 40 southwards to the Oklahoma state line, going through Van Buren and Fort Smith. This particular spur starts at Exit 7 on Interstate 40 (being 7 miles (11 km) east of the state line with Oklahoma). That point marks mile zero on this spur, in keeping with Interstate Highway rules that spur mileage begins at the "parent" route. The first 3 miles (5 km) are through Van Buren, before the bridge over the Arkansas River. The remainder, for a grand total of approximately 15 miles (24 km), travels through Fort Smith. AHTD bid a $79 million project in 2013 for I-540 rehabilitation in Fort Smith that includes re-signing the route and renumbering the exits. [5]

Fort Smith route

Beginning at the I-540 and I-40 junction in Van Buren, the route begins southward along the eastern boundary of Van Buren, with exits numbered sequentially heading south. The segment is largely concurrent with US 71. The first exit along this segment of I-540/US 71 is with US 64 and US 71B (US 71B), which leads west into the Van Buren Historic District and east to Alma. Continuing south, I-540/US 71 passes over Highway 162 (Kibler Road), with no access between the routes. An exit providing access to Highway 59, via Riggs Drive (southbound) or Twin Circle Drive (northbound), is just prior crossing the Arkansas River. After crossing the river, the highways enter Fort Smith and Sebastian County. I-540/US 71 run through a commercial area and has three exits with city collector roads before an exit for Phoenix Avenue, which gives access to Fort Smith Regional Airport. However, this exit does not have any access to southbound I-540/US 71.

Now turning toward the southwest, I-540/US 71 have exits with Highway 45 (Greenwood Road) and Highway 255 (Zero Street). Following these intersections, US 71 departs I-540 southbound toward Texarkana, with US 71B terminating at the parent route at the exit. I-540 begins to pass through a residential area before its final exit at US 271 and Highway 253. Following this exit, the roadway continues but ceases to be I-540, becoming US 271 and entering Oklahoma.[ citation needed ]


The Interstate spur opened in phases. According to a 1970 road map of Fort Smith,[ citation needed ] exits 2-11 (Van Buren through the Zero Street exit) were opened, with later exits (12-14) and the roadway itself still under construction. Portions of the roadway that became I-540 around Fayetteville were built in the early 1970s, but upgraded and extended in the mid-1990s. The highway around Fayetteville originally received US 71 signage until the complete I-540 spur was opened.

Originally, I-540 running from I-40 to Oklahoma through Fort Smith was originally signed east–west, but with the construction of the spur that ran north through Northwest Arkansas to Bella Vista the entire I-540 was resigned as a north–south road. It is one of the few that have changed this way.[ citation needed ]

In the late 1990s, I-540 was extended into Northwest Arkansas. It had been planned since the 1970s as a bypass of U.S. Highway 71. The first section, between Alma and Mountainburg was known as Arkansas Highway 540. Originally, the Arkansas State Highway and Transportation Department (AHTD) asked the American Association of State Highway and Transportation Officials (AASHTO), who are in charge of Interstate and U.S. Highway route numbering, to allow the Interstate segment between Fort Smith and Bentonville to be named I-49, in order to emphasize plans to extend the route from Shreveport, Louisiana, through Arkansas to Kansas City, Missouri. [6] AASHTO refused and the route opened on January 8, 1999, as a northern extension of I-540. [7] On October 18, 2013, AASHTO approved AHTD's application to designate I-49 across the state, specifically allowing the state to renumber I-540 as I-49. [8] The northern section of I-540 was renumbered I-49 in April 2014. [9]

Interstate 40 (I-40) is a major east-west Interstate Highway running through the south-central portion of the United States generally north of I-10, I-20 and I-30 but south of I-70. The western end is at I-15 in Barstow, California; its eastern end is at a concurrency of U.S. Route 117 (US 117) and North Carolina Highway 132 in Wilmington, North Carolina. It is the third-longest Interstate Highway in the United States, behind I-80 and I-90. Much of the western part of I-40, from Oklahoma City to Barstow parallels or overlays the historic US 66, east of Oklahoma City the route generally parallels US 64 and US 70. I-40 runs through or near many major cities including Albuquerque, New Mexico; Amarillo, Texas; Oklahoma City, Oklahoma; Little Rock, Arkansas; Memphis, Tennessee; Nashville, Tennessee; Knoxville, Tennessee; Greensboro, North Carolina; and Raleigh, North Carolina.

Interstate 49 Interstate in Louisiana, Arkansas, and Missouri

Interstate 49 (I-49) is a north–south Interstate Highway that exists in multiple segments: the original portion entirely within the state of Louisiana with an additional signed portion extending from I-220 in Shreveport to the Arkansas state line, four newer sections in Arkansas, and a new section that opened in Missouri. Its southern terminus is in Lafayette, Louisiana, at I-10 while its northern terminus is in Kansas City, Missouri at I-435 and I-470. Portions of the remaining roadway in Louisiana, Arkansas, Missouri, and Texas, which will link Kansas City with New Orleans, are in various stages of planning or construction. When I-49 is complete, the goal of the association will have been accomplished, with only a brief gap and name change in Kansas City.

U.S. Route 412 highway in the United States

U.S. Route 412 is an east–west United States highway, first commissioned in 1982. Its route number is a "violation" of the usual AASHTO numbering scheme, as it comes nowhere near its implied "parent", US 12. U.S. 412 overlaps expressway-grade Cimarron Turnpike from Tulsa west to Interstate 35 and the Cherokee Turnpike from 5 miles (8.0 km) east of Chouteau, Oklahoma, to 8 miles (13 km) west of the Arkansas state line. A curiosity of this highway is that it runs the entire length of the Oklahoma Panhandle and traverses the Missouri Bootheel.

Its southern terminus is in Tyler, Texas, at an intersection with State Highway 31 and SH 155. The highway's northern terminus is in Fort Smith, Arkansas, at an intersection with Business U.S. Route 71 and Highway 255. It enters Arkansas from Oklahoma as a controlled-access highway, but the highway continues as Interstate 540 when US 271 exits toward downtown after one-half mile (800 m) in Arkansas.

U.S. Route 71 US highway that goes from Ontario, Canada to Louisiana, United States

U.S. Route 71 or U.S. Highway 71 is a major north–south United States highway that extends for over 1500 miles 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.
