Expressways of Japan
The road is named the Dōō Expressway (lit. "Central Hokkaidō Expressway") in Japanese; however, its official English name is "the Hokkaido Expressway". It is the only national expressway in Japan in which the English name is not a direct romanization of the Japanese name (such as "Dōtō Expressway"). Its abbreviated name in Japanese is Dōō Dō (道央道, "[Hokkai]dō-Center Way").
Officially the expressway is designated as the Hakodate-Nayoro Route (函館名寄線) of the Hokkaidō Jūkan Expressway. The name Jūkan (縦貫, "lengthways") distinguishes it from the Trans-Hokkaido Expressway, the Ōdan (横断, "transverse").
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. 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 Sasson Expressway is built to an urban expressway standard and tolls are charged at a flat rate. As of March 2008 the toll on this section is 400 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.
