Overview
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 Japan Sea to its terminus with National Route 7 in Noshiro.
The entire route is signed as the Akita Expressway for consistency purposes, however two separate sections of the route are officially designated as the Akita Sotokanjō Expressway and Kotooka Noshiro Road (both bypasses of National Route 7). These sections are not classified as national expressways but rather as national highways for motor vehicles only with national expressway concurrency (高速自動車国道に並行する一般国道自動車専用道路, Kōsoku Jidōsha Kokudō ni Heikōsuru Ippan Kokudō Jidōsha Senyō Dōro).[5]
The route of the expressway is planned to eventually continue past the current terminus at Futatsui-Shirakami Interchange as the Nihonkai Engan Tōhoku Expressway towards a junction with the Tōhoku Expressway near Aomori Prefecture,[5][6] however it is unknown if the naming of the sections that are currently open will change upon completion of that expressway.
The section between Hachiryū Interchange and Futatsui-Shirakami Interchange, and Ōdate-Noshiro Airport Interchange and Ōdate-kita Interchange are toll-free;[2] all other sections assess tolls based on distance travelled in the same manner as most other national expressways.
