The Seto-Chūō Expressway (瀬戸中央自動車道, Seto-Chūō Jidōsha-dō) is a tolled expressway that connects Okayama and Kagawa prefectures in Japan across a series of five small islands in the Seto Inland Sea. Built between 1978 and 1988, it is one of the three routes of the Honshu-Shikoku Bridge Expressway Company connecting Honshū and Shikoku islands. The route is signed E30 under Ministry of Land, Infrastructure, Transport and Tourism's "2016 Proposal for Realization of Expressway Numbering."
