US 82 runs across the southern tier of counties in Arkansas, serving three cities of regional importance: Texarkana, Magnolia, and El Dorado in the Arkansas Timberlands. The eastern half of the route runs through the Lower Arkansas Delta, serving small towns and agricultural areas. US 82 enters the state from Texarkana, TX concurrent with US 67 as a pair of one-way streets. Running east as 7th Street, the road enters Arkansas at an intersection with State Line Avenue. The junction provides US 67/ US 82 with access northward to US 59/US 71 via US 71Y. At Hazel Street, US 67/US 82 intersects US 59/US 71, beginning a brief concurrency east to Hickory St, when US 59/US 71 turns south toward Shreveport, LA. The intersection is near the J.K. Wadley House, listed on the National Register of Historic Places. The two one-way streets combine at Hickory St and run east as 9th Street to Broad Street, where US 67 turns northeast. Continuing east, US 82 intersects Interstate 49 with a diamond interchange, the only junction with an Interstate highway in Arkansas.

Entering Crossett, the route has an overlap with Highway 169 and passes a Georgia Pacific plant. North of downtown, Highway 82 intersects Highway 133 Truck, followed by a short overlap with Highway 133. The highway exits the town heading due east, turns north and begins an overlap with Highway 52 and US 425. Shortly after turning north, Highway 52 breaks from the concurrency toward the west, with US 82/US 425 continuing north to Hamburg. Upon entering the city, US 82/US 425 begins overlaps with Highway 52, passing the First United Methodist Church and Hamburg Commercial Historic District.

History
The route was designated on July 1, 1931. In Arkansas, it replaced State Road 2. US 82 was realigned around Waldo and Magnolia on February 25, 1954 on to present-day US 371. The former alignment of US 82 was redesignated at Highway 98. On May 20, 1970, this segment was bypassed by a new terrain US 82. The former routings were renumbered Highway 98 and Highway 19, and the Magnolia business route was created.
El Dorado was bypassed in the 1980s; Highway 2 is now a business route.
The segment between Crossett and Hamburg has been rerouted several times, most recently in the 1970s. Highway 2 is now parts of Highway 133 and Highway 52 north of Crossett, a short spur of Highway 189 in Hamburg, and a county road from the end of Highway 189 south to Highway 52.
Montrose was bypassed in the 1940s by a railroad overpass; Highway 2 is now a minor business route.
In 1989, the Arkansas General Assembly passed Act 622. This act authorized governor Bill Clinton to sign a compact with Texas, Mississippi, and Alabama to four-lane US 82 across the four states. The compact also created the U.S. Highway 82 Four Lane Construction Authority to assist the effort. Mike Kinard, state senator from Magnolia, sponsored the bill. Mississippi joined the effort in 1989, appointing three citizens to the Authority. However, it appears the Authority was never created; with Texas, Alabama, and United States Congress coordination and approval never coming to pass.
