In 2021 a New Shiyui beam bridge was opened parallel to the older arch. The newer crossing is part of a major upgrade to route 45 near the coast of Iwate Prefecture.

The Shiyui crosses a deep canyon in Japan’s Iwate prefecture. Like so many Japanese arch bridges from the 1980s, Shiyui has 2 steel box beam ribs. Measuring 607 feet (185 mtrs) between hinges, the ribs support deck spans of 37.7 feet (11.5 mtrs) along with a steel ‘keystone’ 36 feet (11 mtrs) long.


田野畑大橋は岩手県の深い峡谷に架かっています。日本の80年代からの多くのアーチ橋のように、田野畑大橋には2つの鋼箱ビームリブがあります。ヒンジ間の長さは185m、そして長さ11mの鋼鉄“キイストーン”とともにリブ補強デッキは11.5mにわたります。
