An expressway that crosses the center of Kyushu from east to west. It is managed by West Nippon Expressway Co., Ltd. There are two routes: (1) the Nagasaki-Oita Line, which starts in Nagasaki City, connects with the Kyushu Expressway (Kyushu Expressway) in Tosu City, Saga Prefecture, enters Oita Prefecture along the Chikugo River, goes from Yufu Plateau to Oita City, and connects with the Higashi Kyushu Expressway; and (2) the Nobeoka Line, which branches off from the Kyushu Expressway in Kashima Town, Kumamoto Prefecture, crosses the Kyushu Mountains, and reaches Nobeoka City, Miyazaki Prefecture, where it connects with the Higashi Kyushu Expressway. The total length is 352 kilometers (the Nagasaki-Oita Line is 257 kilometers, the Nobeoka Line is 95 kilometers), and all sections are four lanes (some sections are temporarily two lanes). In 2004, the Nagasaki-Oita Line was completed for a total of 257 kilometers between Nagasaki City and Tosu City (Nagasaki Expressway) and between Tosu City and Oita City (Oita Expressway), but the Nobeoka Line has not yet been opened. The Nagasaki-Oita Line directly connects western and eastern Kyushu with central Kyushu, and also connects tourist centers such as Nagasaki City and Beppu City, playing a major role in the development of the areas along the line. The section from Kashima to Yabe (Yamato Town, Kamimashiki County, Kumamoto Prefecture) is being constructed under the new direct management method, with the Minister of Land, Infrastructure, Transport and Tourism taking the lead in the development.

九州地方の中央部を東西に横断する高速道路。管理は西日本高速道路。(1)長崎市に発し、佐賀県鳥栖(とす)市で九州縦貫自動車道(九州自動車道)と接続し、筑後(ちくご)川沿いに大分県に入り、湯布(ゆふ)高原から大分市に至り、東九州自動車道と接続する長崎大分線と、(2)熊本県嘉島(かしま)町で九州縦貫自動車道から分岐し、九州山地を横切って宮崎県延岡(のべおか)市に至り、東九州自動車道と接続する延岡線の2路線がある。総延長352キロメートル(長崎大分線が257キロメートル、延岡線が95キロメートル)、全区間4車線(一部は暫定的に2車線)である。 2004年(平成16)に長崎大分線は長崎市―鳥栖市間(長崎自動車道)と、鳥栖市―大分市間(大分自動車道)の、計257キロメートルが全通したが、延岡線は未開通である。長崎大分線は、九州の西部と東部を九州中央部と直結し、長崎市、別府市などの観光拠点も相互に連絡して、沿線地域の開発の発展に大きな役割を果たしている。嘉島から矢部(熊本県上益城(かみましき)郡山都(やまと)町)の区間は国土交通大臣が整備主体となる新直轄方式で建設されている。 [下保 修] [参照項目] |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
