The Loop consists of I-30, I-369, Loop 151, and AR 151. US 59 is concurrent with the beltway from the southwest corner of Texarkana to State Line Avenue. I-30 forms the northern portion of the route, running north of both the twin cities. The eastern section of the Loop consists of I-49 and AR 151, and runs. it runs from US 59/71 north of I-30 to an interchange with I-49 on the southeast side of Texarkana. The southern section of the loop consists of Loop 151 and AR 151. It runs from I-49 in southeast Texarkana to I-369 in southwest Texarkana. The western section of the loop is formed by I-369. I-369 continues north on the western side of Texarkana to a stack interchange with I-30 in northwest Texarkana.
History
Previously in Texas, the "151" designation was originally used for Spur 151, which was designated on May 18, 1944 from Denison to the southern boundary of the Federal Government Property. Spur 151 was cancelled on May 21, 1946 and instead replaced by SH 75A, which in turn became SH 91 on December 21, 1994. Loop 151 was designated on August 27, 1958 from I-30 to US 82. On January 20, 1966, Loop 151 extended south to US 59. On December 21, 1982, Loop 151 was transferred to US 59, so Loop 151 was reassigned to the old route of US 59. On February 7, 1985, Loop 151 was transferred to SH 93, so Loop 151 was reused for the route from US 59 to Arkansas, its current route. In fall 2000, the Arkansas State Highway and Transportation Department had submitted its portion of the loop as Interstate 130 in fall 2000. However, the American Association of State Highway and Transportation Officials denied the part from US 71 west to Texas, as "the state of Texas has not submitted a companion application for a suitable terminus in Texas", but the piece from US 71 north to I-30 was approved on December 8, 2000 as Future I-130. Once it was upgraded to Interstate standards and added to the Interstate Highway System by the Federal Highway Administration, it was to be signed as I-130.Arkansas used American Recovery and Reinvestment Act of 2009 funds to pave the final segment of future I-130, from the Arkansas Boulevard interchange to a new freeway-to-freeway interchange with I-30. Once this section was opened, the only remaining requirement to become I-130 would have been to upgrade the at-grade intersection with 19th Street to a full interchange; the right-of-way for this was reserved years ago. However, with I-49 also pending completion between Texarkana and Shreveport, Louisiana, future I-130 was instead made part of I-49 by summer 2014. In May 2013, the final designated portion of AR 245 was removed from service and re-designated Four States Fair Blvd. Highway 245 was the former designation of Arkansas's section of the loop. Interstate 369 was designated on May 30, and signs of the highway were installed on September 23, 2013.
