The Dō-Ō Expressway (道央自動車道, Dōō Jidōsha-dō) is a national expressway in Hokkaido, Japan. It is owned and operated by East Nippon Expressway Company.
Naming
The road is named the Dō-Ō Expressway (lit. "Central Hokkaidō Expressway") in Japanese; however, it's also known as the Hokkaido Expressway.
Officially the expressway is designated as the Hakodate-Nayoro Route (函館名寄線) of the Hokkaidō Jūkan Expressway.[2] The name Jūkan (縦貫, "lengthways") distinguishes it from the Trans-Hokkaido Expressway, the Ōdan (横断, "transverse").
Route description
The expressway connects the north of Hokkaido with the south via the city of Sapporo. Extension of the expressway in the north towards the city of Wakkanai and in the south towards the city of Hakodate is underway; although the Hokkaido Expressway itself is not planned to extend as far as these two cities, various expressway-standard roads (bypasses of National Route 40 to the north and National Route 5 to the south) will cover the remaining distances.
Some unfinished sections of the expressway (Shibetsu-Kenbuchi Interchange to Nayoro Interchange in the north and Ōnuma Interchange to Nanae Interchange in the south) will be constructed according to the New Direct Control System.[3] These sections are expected to operate toll-free upon completion.
The section from Sapporo-minami Interchange through Sapporo Junction to Sapporo-nishi Interchange on the
yen for regular passenger cars. Tolls on all other sections of the expressway are assessed according to distance travelled in the same manner as most other national expressways.[4]
