OverviewEdit

The expressway is incomplete in many areas, however it is planned to eventually be a continuous route spanning northern Fukushima, Yamagata, and southern Akita prefectures. As of July 2019, all gaps in the expressway are in the process of being eliminated, with all gaps in Fukushima set to be removed by 2020.[3] North of the city of Shinjō, various expressway-standard roads (bypasses of National Route 13) make up the remaining distance to the city of Yokote in Akita Prefecture.[4]

The route of the expressway parallels the Ōu Main Line of East Japan Railway Company for most of its length.

The speed limit is 70 km/h along the majority of the route, there are short 80 km/h sections between Yonezawa-kita and Yonezawa-Hachimanbara interchanges and Higashine and Higashine-kita interchanges.

HistoryEdit

The first section of the Tōhoku-Chūō Expressway to open was between Yonezawa-kita and Yonezawa-Hachimanbara interchanges on 21 November 1997. Since then the road has gradually been extended by adding short extensions.[5] The 8.8 km (5.5 mi) long Yonezawa-Nan'yō Road was incorporated into the Tōhoku-Chūō Expressway on 4 November 2017.[6] MLIT began construction on the last gap of the road on 30 March 2018, a 3.5 km (2.2 mi) long section in Kaneyama, Yamagata.[4]
