E30 Seto-Chuo Expressway (Seto-Ohashi Bridges)
A group of two-level, long-span bridges with expressway on upper deck and railway on lower deck
It is a combined expressway and railway route passing through the center of the elegant archipelago in the Seto Inland Sea, which was the first in Japan to be designated as a national park. Leading the way for the Honshu-Shikoku Bridge three routes, it was opened in 1988. The route is 37.3 km of expressway and 32.4 km of railway, and the six bridges that span the 9.4km strait are known collectively as the Seto-Ohashi Bridges. The sight of one of the world's longest group of long-span bridges, suspension, cable-stayed and truss bridges, is truly spectacular.
