The first section of the expressway was opened to traffic in 1988. As of March 2007 the expressway incomplete in many areas. The next sections are scheduled to open in 2009 (Tanoura InterchangetoAshikita Interchange). After this, Most of the incomplete areas will be built according to the New Direct Control System, whereby the burden for construction costs will be shared by the national and local governments and no tolls will be collected. Currently the section between Hinagu Interchange and Tsunagi Interchange, Noda Interchange and Akune Interchange, and Satsumasendai-Mizuhiki Interchange and Ichiki Interchange operates according to this principle.
The route parallels the Kagoshima Main LineofKyushu Railway Company and National Route 3 for much of its length.
