Highway 330 begins at an intersection with Greenwood Road and Lakeview Lane in Fairfield Bay, a small retirement community on Greers Ferry Lake in North Central Arkansas.

ArDOT estimates the traffic level for a segment of roadway for any average day of the year in these surveys.

[10] In 1953, the segment west of US 65 was redesignated as Highway 9, trimming the route to approximately 1 mile (1.6 km).

[12] On June 23, 1965, it was extended east 1.8 miles (2.9 km) along a county road to the Choctaw Recreation Area.

[15] This roadway remained under state maintenance until September 24, 1997, when the City of Clinton agreed to resume local maintenance in exchange for the Arkansas State Highway and Transportation Department constructing an intersection improvement project at the former highway's eastern terminus.
