The route continues south to Watkins Corner, where it intersects Highway 318Y, a short connection providing access to Highway 316 for westbound traffic. Highway 318 intersects Highway 316 and the Great River Road, including a brief officially designated exception. After this short eastbound concurrency, Highway 318 continues due south again, now concurrent with the Great River Road, as a section line road, bridging Big Creek and crossing two levees before a junction with Highway 20 near Lambrook, where the route terminates. The Great River Road continues west along Highway 20 to Elaine.

History
The section between Oneida and Highway 44 was created by the Arkansas State Highway Commission on November 23, 1966. A new section was created near Watkins Corner south to a county road on June 28, 1973, pursuant to Act 9 of 1973 by the Arkansas General Assembly. The act directed county judges and legislators to designate up to  of county roads as state highways in each county.
The highway was extended south to Highway 20 on February 27, 1974. 
The route was extended north on August 28, 1974 during a renumbering of routes in the area to improve continuity. The Highway 318 extension supplanted Highway 243 north of Watkins Corner. In 1974, the AHTD temporarily used a Bailey bridge for  over Big Creek following a bridge failure. The temporary structure was replaced with a permanent precast concrete bridge later that year.
