Route description

The Akashi Kaikyō Bridge has the longest central span of any suspension bridge in the world. It is a vital part of the Kobe-Awaji-Naruto Expressway

The Ōnaruto Bridge connects Minamiawaji, Hyogo on Awaji Island with Naruto, Tokushima on Ōge Island

The expressway is 89.0 kilometres (55.3 mi) long with 24.3 kilometres (15.1 mi) of that stretch consisting of bridges, chiefly the Akashi Kaikyō Bridge and Ōnaruto Bridge. The expressway has four lanes along the entire route from Kobe to Naruto in Tokushima, with an exception along the Akashi Kaikyō Bridge, were it has six lanes. The speed limit is 70 km/h between Awajishima-minami Interchange and Naruto-kita Interchange, 100 km/h between Awaji Interchange and Seidan-Mihara Interchange as well as between Kobe-Nishi Interchange and Tarumi Junction. The remainder of the expressway has a speed limit set at 80 km/h.[2]

History

On 8 June 1985 the first sections of the expressway opened. These were between Tsuna-Ichinomiya Interchange and Sumoto Interchange and between Naruto-kita Interchange and the now defunct Seidan Interchange. The latter of the two sections includes the Ōnaruto Bridge. On 23 May 1987, the road was extended south from Naruto-kita Interchange to its southern terminus at Naruto Interchange. Next, on 8 October 1987, the highway between Sumoto IC and Seidan-Mihara Interchange was opened. The opening of Seidan-Mihara Interchange necessitated the closure of Seidan Interchange. On 5 April 1998 the highway between Kobe-Nishi Interchange and Tsuna-Ichinomiya Interchange was opened with the completion of the Akashi Kaikyō Bridge. The most recent development on the expressway came on 17 February 2018, when the ETC-only Awajishima-chuo Smart Interchange was opened.[3]
