History
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]
