Tōhoku Expressway
The expressway begins at a junction with the Tōhoku Expressway in Iwate Prefecture and crosses into Akita Prefecture to the west. The route intersects the Yuzawa-Yokote Road in Yokote and the Nihonkai-Tōhoku Expressway in the Akita city area. From this junction, the route follows a northerly course parallel to the Sea of Japan to National Route 7 in Noshiro where the expressway meets a gap in its routing. The expressway resumes its course, heading northeast towards the Tōhoku Expressway near Odate–Noshiro Airport in Kitaakita. The Akita Expressway ends at a junction with the Tōhoku Expressway in the town of Kosaka.
