Shin-Onomichi Bridge, Cable-stayed bridge in Onomichi, Japan.
Shin-Onomichi Bridge is a cable-stayed structure crossing the Onomichi Channel with two prominent towers painted in a distinctive honey tone. The span carries four lanes of traffic connecting Honshu to Mukaishima island.
This bridge was built in the late 1990s to handle traffic that overwhelmed the original Onomichi Bridge. It opened in 1999 and provided immediate relief to the older crossing.
The bridge forms an integral part of the Nishiseto Expressway, connecting Honshu with the island of Mukaishima through a modern engineering structure in the Seto Inland Sea.
The bridge is easily reached from the Sanyo Expressway and carries National Route 317 for straightforward vehicle passage. Visitors without a car can arrange travel between Onomichi and Mukaishima, or walk onto the bridge from nearby viewpoints.
Inside the steel structure, a special dehumidification system circulates dry air to prevent rust from forming within the beams. This innovation had never been used in Japanese bridge construction before.
