Nagano Expressway - Overview

Overview

The expressway was originally built and managed by Japan Highway Public Corporation. On October 1, 2005, the management of the route was assigned to East Nippon Expressway Company (Kōshoku Junction to Toyoshina Interchange, excluding the interchange) and Central Nippon Expressway Company (Okaya Junction to Toyoshina Interchange, including the interchange).

The route of the expressway runs through the central part of Nagano Prefecture. From the origin at a junction with the Chūō Expressway in the city of Okaya near Lake Suwa, the expressway follows a northerly course to Matsumoto, the major city in the central Nagano area. From here the expressway follows a winding northeasterly course through mountainous areas before reaching the terminus in the city of Chikuma. Beyond the terminus, the roadway continues as the Jōshin-etsu Expressway towards the city of Nagano, the prefectural capital.
