E76 Nishi-Seto Expressway (Setouchi Shimanami Expressway)
A road crossing the Geiyo islands
A 46.6km toll road that threads its way through the Geiyo Islands where the "Murakami Pirates", the strongest in the Seto Inland Sea, once had brave adventures. This expressway, with a total length of 59.4 km directly connected with the Ikuchi-jima road (6.5 km) and the Ohshima road (6.3 km) maintained by Ministry of Land, Infrastructure, Transport and Tourism, is affectionately known as the "Setouchi Shimanami Expressway". On bridges other than the Shin-Onomichi Bridge, there is also tracks exclusively for use by motor-assisted bicycles and pedestrians from Onomichi to Imabari, and as well as its role as a connecting road linking Honshu and Shikoku, it serves a major role as a community road for the people living on the islands.
