TheDō-Ō Expressway (道央自動車道,Dōō Jidōsha-dō) is a nationalexpressway inHokkaido, Japan. It is owned and operated byEast Nippon Expressway Company.
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 theHakodate-Nayoro Route (函館名寄線) of theHokkaidō Jūkan Expressway [ja].[2]The nameJūkan (縦貫; "lengthways") distinguishes it from theTrans-Hokkaido Expressway [ja], theŌdan (横断; "transverse").
The expressway connects the north of Hokkaido with the south via the city ofSapporo. Extension of the expressway in the north towards the city ofWakkanai and in the south towards the city ofHakodate is underway; although the Hokkaido Expressway itself is not planned to extend as far as these two cities, various expressway-standard roads (bypasses ofNational Route 40 to the north andNational 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 theSasson Expressway is built to an urban expressway standard and the tolls are charged at a flat rate. As of March 2008 the toll on this section is 400yen 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]
