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.[1]
Route[edit]
The route spans 46.5 kilometres (28.9 miles), with a maximum altitude difference of 67 metres (220 feet).[2] Along its length are seven bridges with a cumulative length of 5,300 m (17,400 ft), connecting the islands of Shimokamagari, Kamikamagari, Toyoshima, Ōsakishimojima, Herashima and Nakanoshima before terminating at Okamura Island.[1] The seventh of the bridges, Okamura Bridge, crosses the border from Hiroshima Prefecture to Ehime Prefecture. The entire route has gentle gradients, marked cycle lanes and is equipped with five designated cycle stations[2], making this a popular cycling destination.[3]
An eighth bridge connecting Okamura to Ōsakikamijima is planned, but construction has not started.[4] An alternative series of bridges to Ōmishima Island has also been proposed.[5] Currently, there are ferry services from Okamura to Ōmishima and the city of Imabari, Ehime in Shikoku.[6]
Nickname[edit]
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.
