	二つの山あいのトンネルに挟まれた長さ380ｍのアーチは、沼田川より195ｍ上にかかっています。主要なアーチはステイドキャンティレバーと呼ばれる方法によって建設されました。これによると、タワーが一方の峡谷に建てられ、これより一時的に放射上に伸びたケーブル（大綱）が各部分のアーチを支えます。そして二つに分かれているアーチが中央で結合されるまでアーチを支えます。二つのタワー上の間にかけられた高架ケーブルは沼田川上空において、鋼鉄部分を移動設置するために使われました。これは日本で最長のアーチ橋となります。また、将来錆びついた橋に再塗装を行わなくてもすむように腐食予防鋼鉄が使われています。		二つの山あいのトンネルに挟まれた長さ380ｍのアーチは、沼田川より195ｍ上にかかっています。主要なアーチはステイドキャンティレバーと呼ばれる方法によって建設されました。これによると、タワーが一方の峡谷に建てられ、これより一時的に放射上に伸びたケーブル（大綱）が各部分のアーチを支えます。そして二つに分かれているアーチが中央で結合されるまでアーチを支えます。二つのタワー上の間にかけられた高架ケーブルは沼田川上空において、鋼鉄部分を移動設置するために使われました。これは日本で最長のアーチ橋となります。また、将来錆びついた橋に再塗装を行わなくてもすむように腐食予防鋼鉄が使われています。

−	Upon its opening in 2010, the Hiroshima Airport bridge became the highest bridge ever built in Japan, surpassing the Kokonoe "Yume" Otsurihashi footbridge built just three years earlier in Oita prefecture. The arch is part of a new 19 mile (30 km) Central Flight highway that will connect the new 1993-built Hiroshima airport to highway 184 - a major route in the region.	+	Upon its opening in 2010, the Hiroshima Airport bridge became the highest bridge ever built in Japan, surpassing the Kokonoe "Yume" Otsurihashi footbridge built just three years earlier in Oita prefecture. The arch is part of a new 19 mile (30 km) Central Flight highway that will connect the new 1993-built Hiroshima airport to highway 184 - a major route in the region. Also completed in 2010, the Shintabisoko Bridge became Japan's highest bridge at 210 meters.

	Bookended by two mountain tunnels, the massive 1,247 foot (380 meter) long arch spans 640 feet (195 meters) above the Nuta River. The main arch was constructed using the stayed cantilever method whereby a tower is erected on either side of the gorge and cables temporarily radiate out from it to support individual sections of the arch until the two halves can be joined in the middle. A cable highline between the tops of the two towers was used to move the steel sections into place high above the river. It is the longest arch of any kind ever built in Japan. Corrosion resistant steel was used to avoid the difficulty of repainting the bridge in the future.
