The Nishikyushu Expressway (西九州自動車道, Nishi-Kyūshū jidōshadō) is one of the expressways of Japan which goes from FukuokatoTakeo running through the prefecture of Saga and the northern half of the Nagasaki prefecture. The total length is 150 km.
Part of the road is specified as Route 497. This road has two toll zones. The Fukuoka and Maebaru toll zone is managed by Fukuoka Prefectural Road Public Corporation. The Takeo and Sasebo toll zone is managed by West Nippon Expressway Company. The other roadway is managed by MLIT. This road is connected to Fukuoka Expressway Circular RouteinNishi-ku, Fukuoka, and to Nagasaki Expressway in Takeo. From Nijō to Nijō Shika Interchange this expressway overlaps a section of Nijō Hamatama road.
The first section of the expressway was opened to traffic in 1988. As of April 2016 the expressway was incomplete in many areas. The next sections were scheduled to open in 2017 (Minamihata Taniguchi InterchangetoImari Higashi Interchange) and (Imabuku InterchangetoTsukinokawa Interchange). After this, most of the incomplete areas were to 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 were to be collected. Currently the section between Nijō Shikaka Interchange and Minamihata Taniguchi Interchange, Yamashiro Kubara Interchange and Imabuku Interchange, and Saza Interchange and Sasebo Daitō Interchange operates according to this principle.
The expressway is four lanes wide from Fukushige Junction to Higashi Intersection (temporary interchange) and Saza InterchangetoSasebo Chūō Interchange, and two lanes for all remaining sections.
