Akinada Tobishima Kaido

The Akinada Tobishima Kaidō (安芸灘とびしま海道), officially the Akinada Islands Link Bridges (安芸灘諸島連絡架橋, Akinada-shotō-renraku-kakyō), is a road connecting Kure, Hiroshima to seven of the Geiyo Islands in the Seto Inland Sea, Japan.

[1] The route spans 46.5 kilometres (28.9 miles), with a maximum altitude difference of 67 metres (220 feet).

[6] After a public naming competition that received 3,118 entries, the route was given the official nickname Akinada Tobishima Kaidō in 2008.

[7] Akinada (Aki Sea) is the open expanse west of the Geiyo Islands, while tobishima comes from tobi-ishi (飛び石), the Japanese name for stepping stones in a garden.

[1][8] The route is also unofficially known as the Ura-Shimanami Kaidō (裏しまなみ海道) after the nearby Shimanami Kaido expressway, which connects Onomichi (Hiroshima) and Imabari (Ehime), going through nine of the Geiyo Islands, including Ōshima, Ōmishima, and Innoshima.
