Naming
The expressway is officially referred to as the Chūō Expressway Nagano Route. The Chūō Expressway Nagano Route is the official designation for the Chūō Expressway between Takaido Interchange and Okaya Junction (concurrent with the Chūō Expressway Nishinomiya Route), the Nagano Expressway between Okaya Junction and Kōshoku Junction, and the Jōshin-etsu Expressway between Kōshoku Junction and Suzaka-Naganohigashi Interchange (concurrent with the Kan-Etsu Expressway Jōetsu Route).[3]
Overview
Nagano Expressway
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).[4][5]
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.
