AR 346 was created by the Arkansas State Highway Commission on November 23, 1966 along a county road from AR 8 to the Caddo River.[1] In 1973, the Arkansas General Assembly passed Act 9 of 1973. The act directed county judges and legislators to designate up to 12 miles (19 km) of county roads as state highways in each county.[3] One of the extensions in Clark County extended AR 346 across the Caddo River to AR 84.[4] In 1992, the Highway Commission granted the Clark County judge's request to transfer jurisdiction of the segment between AR 8 and the Caddo River in exchange for creation of AR 26 Spur (AR 26S) in Gum Springs.[5]
