夏納洛大橋位于奧地利多恩比恩市愛彼列村的夏納洛峽谷，是連通多恩比恩市與愛彼列村的重要道路。在多恩比恩河與優(yōu)美的群山的襯托下，夏納洛大橋別具一格地融入了當(dāng)?shù)氐淖匀痪坝^當(dāng)中。這座壯觀的大橋聯(lián)系著愛彼列村的古老聚落區(qū)域，并以眾多的天然巖石隧道與石橋著稱。

大橋的設(shè)計(jì)采用了石拱橋的形式，并融合現(xiàn)代科技將拱形的幾何結(jié)構(gòu)展現(xiàn)到了極致。設(shè)計(jì)將大橋拱高降低到最小，并將拱底設(shè)計(jì)為扭曲的形狀，營造出動(dòng)靜結(jié)合的效果。而扭曲的設(shè)計(jì)隨著橋道駕駛道形成曲線，與彎曲的道路相呼應(yīng)。這樣，這個(gè)鋼筋混凝土結(jié)構(gòu)橫跨了整個(gè)小峽谷，而駕駛者在通過時(shí)很難察覺這種特色，但從蜿蜒的河岸上仰視大橋時(shí)，則能夠感受到大橋的魅力之處：它不僅模仿了山路蜿蜒的動(dòng)態(tài)感，還通過鋼筋水泥的結(jié)構(gòu)突顯了這個(gè)地域的鮮明特征。

The bridge through the Schanerloch gorge is part of the impressive road from the city of Dornbirn to the hamlet of Ebnit which picturesquely situated by the well of the river Dornbirner Ache at the foot of scenic mountains.The spectacular route to this ancient settlement area is characterized by a series of natural rock tunnels and stone bridges.

Originating from the well known typology of the stone arch bridge, modern technology takes the geometry of the arch to its very limits. The reduction of the arch rise to a statically necessary minimum is combined with a twist along one axis.The latter is also responding to the bending road as a curve immediately follows the bridge in both driving directions. The result is a concrete sculpture that might look unspectacular in plan and from the driver's point of view, but from the shore of the river winding through the gorge it unveils its compelling fascination: it playfully mimes the frozen dynamic of the mountain road and captures the dramatic place in reinforced concrete.
