The route's western terminus is at US 82/US 371 in north Magnolia. The route runs south with US 371 in a concurrency along Vine Street.[3] Upon reaching Main Street the concurrency ends; US 371 turns west and US 82B turns east. US 82B passes the Dr. H.A. Longino House before entering the Magnolia Commercial Historic District and circling around the Columbia County Courthouse. All three properties are listed on the National Register of Historic Places (NRHP).[4] Continuing east, US 82B has a junction with Jackson Street, which runs north as Highway 355 and south as US 79, which provides access to Highway 19 just south of this junction.[2] Highway 355 provides access to Magnolia Hospital and Southern Arkansas University in north Magnolia. US 82B continues due east through a commercial area, including a strip mall and various restaurants. The route turns southeast after Fairview Street, a direction it follows until meeting US 79/US 82 where it terminates near the city limits.
