Arkansas Highway 20 (AR 20, Hwy. 20) is an east–west state highway in Phillips County, Arkansas. The route of 31.76 miles (51.11 km) runs from Lambrook northeast to US 49 in Helena-West Helena.[2] Segments of the route make up the western routing of the Great River Road.[3]

Route description[edit]

AR 20 begins near Lambrook facing south at County Route 622 when the route turns due east. After the highway passes the Lambrook post office, the route serves as the routhern terminus for Highway 318 and turns southeast toward Elaine. The city brings a junction with Highway 44, after which AR 20 becomes a minor state highway winding along the Mississippi River. The route passes through the unincorporated community of Modoc before forming its only spur route. This spur runs due south to the Mississippi River. The parent thighway AR 20 continues as a two-lane rural route, meeting AR 44 in south Helena-West Helena before terminating at US 49.

Great River Road[edit]

The Great River Road runs on AR 20 from US 49 to AR 44 in the extreme southern part of Helena-West Helena. The scenic byway follows AR 44 south to Elaine, when the Great River Road joins with AR 20 westbound. The route remains scenic until the junction with AR 318 east of Lambrook.[3]

Highway 20 was one of the original state highways, designated in 1926.[4] The route began at Highway 3 in east Monroe County and ran east through Marvell and Barton on its way to Helena, when the route turned south. Highway 20 continued south along its current routing from Helena, then along its present spur route to terminate at the Mississippi River.[4] Highway 3 was later replaced by US 49/AR 1 in the area, at which time AR 20 was extended south. Highway 20 was later extended west to the Lambrook area.
