Seto Ōhashi is a series of double deck bridges spanning 13.1 kilometers and connecting the Japanese prefectures of Okayama and Kagawa across five small islands in the Seto Inland Sea. It is part of the Honshū-Shikoku Bridge Project and takes about 20 minutes by car or train to cross, much faster than the previous 1 hour ferry crossing. The toll is 3,500 yen from Kojima, Kurashiki to Sakaide.
