Opened on January 15th, 2010, the Shintabisoko Bridge became the highest bridge ever in Japan and the first in the country to exceed 200 meters in height. Built as part of a new bypass for route 418, the original road was an unmaintained series of serpentine twists and turns in a mountainous region of Gifu prefecture. The construction of the Shin-Maruyama Dam also made the new highway a necessity as parts of the old 418 were inundated under the reservoir. An arm of this new lake is located under the new bridge. The full reservoir depth was reported to be about 50 feet (15 mtrs) where it crosses beneath the bridge but photos reveal that the reservoir water has never backed all the way up the creek to the bridge crossing.

The bridge was constructed using the cantilever method and the 2-lane, single cell box girder has a depth of 17 feet (6 mtrs) in the center and 43 feet (13 mtrs) over the piers. The tallest pier is 331 feet (101 mtrs) and is said to be the 3rd highest in Japan.

In 2020 Bungy Japan began operations on the Shintabisoko Bridge. The company offers bungy jumping from many high bridges in Japan including Ryujin, Itsukimura, Sarugakyo, Fuji Sudokeikoku, Minakami, Kaiun and Yamba Bridges.

Shintabisoko Bridge Elevation


2010年1月15日に開通した新旅足橋は、日本で初めて200メートルを超える高さを持つ橋であり、同国内で最も高い橋となりました。 国道418号の付け替え道路の一部として建設された橋で、元の道路は岐阜県の山中にあり維持管理がされず蛇のようにうねうねと曲がりくねった区間が続いていました。 新丸山ダムの建設により旧国道418号の一部が貯水池の湖底に沈むため、新道の整備が必要になりました。新しい貯水池の一部はこの新しい橋の下方に位置しています。この橋の直下で交差する貯水池が約50フィート(15メートル)の満水位に達すると、水面上の橋面の高さはおよそ607フィート(185メートル)になります。 橋面から水面までの高さがおよそ640フィート(195メートル)ある広島空港大橋がやはり日本で一番高いと思われる方もおられるでしょう。 でも、ダムは雨が降らない渇水期や維持管理が行われる時に周期的に水位が下がりますので、新旅足橋は200メートルの高さがあるということになります。

この橋はカンチレバー(片持ち梁)方式の工法を用いて施工され、2車線の単純な箱型断面を持つ桁は、支間中央部で17フィート(6メートル)、橋脚部で43フィート(13メートル)の桁高があります。全高が最も高い橋脚は331フィート(101メートル)あり、日本で3番目の高さがあると言われています。
