Highway 334 begins at Highway 1B (Washington Street) in Forrest City, a city of regional importance in the Arkansas Delta region. The highway winds southeast toward the Lee County line through Crowley's Ridge. The loess hill terrain makes the route wind and curve more than the surrounding highways in St. Francis County covering the Mississippi Alluvial Plain. Highway 334 intersects St. Francis County Road 735 (CR 735) at Tuni, with CR 734 and CR 736 continuing west and east, respectively.[3]
Highway 334 begins at US 79 on the St. Francis-Lee County line in the Arkansas Delta. The route runs southeast across Millseed Lake. It turns south along a section line road to Lee County Road 621 (CR 621), where it terminates near a levee. The eastern terminus is less than one mile (1.6 km) from the Mississippi River and the Mississippi state line.[5]
Near the eastern terminus, the AADT was measured as 120 VPD in 2016, dropping to 70 further east.[6]
Both highways were created during a period of expansion in the state highway system in the 1960s. Highway 334 was first created in St. Francis County on June 23, 1965.[1] The Lee County segment was created on November 23, 1966.[7] Neither alignment has changed since creation.
