formerly a wetland preserve, but now the land is being developed.

Today, I-530 and US 65 run concurrently as a four-lane, limited-access spur route. The route formally gained the I-530 designation after a full Interstate-grade bypass of Pine Bluff (known locally as the Wiley Branton Highway) replaced a segment of US 65 through Pine Bluff that contains at-grade intersections. This segment (known locally as the Martha Mitchell Expressway) was redesignated US 65B; US 65 was rerouted to the bypass before gaining the I-530 codesignation. Exit list Future Arkansas Highway 530 A planned extension of the route pushes the Interstate south to US 278 in Wilmar. The first segment of the extension from US 278 north to AR 35 opened as a two-lane expressway designated Arkansas Highway 530 (AR 530) on June 6, 2006. This extension is intended to connect to the proposed southern extension of I-69; US 278 at Wilmar also provides four-lane access to the future I-530 from the larger cities of Warren and Monticello, thus allowing both to champion its completion. Though sufficient right-of-way was provided and grading done for interchanges at both ends as well as two additional lanes, this segment presently has stop signs at both ends and an intersection with Bradley County Road 96 (CR 96)/Barkada Road; it is otherwise a two-lane expressway in between. The second segment of the extension opened in September 2013. It connects the I-530 interchange in Pine Bluff with AR 11 in Lincoln County and is in length. Currently, the segment is two lanes until further funding is available. The remaining segments between AR 35 and Pine Bluff will also be built as a partial two-lane freeway, similar to the existing AR 35–US 278 segment and Pine Bluff intersection to AR 114 segment. Initially, the only full interchange will be with the present I-530 at Pine Bluff; grade crossings will be built at other planned interchanges, but the stretches between grade crossings will be true two-lane expressways with grade separations and service roads where needed. The route includes sufficient right-of-way to build interchanges and two additional lanes later; the Pine Bluff interchange will be a full freeway-to-freeway facility designed for the future four-lane freeway. On August 18, 2015, the next segment—AR 114 to AR
