The Trisanna Bridge (German: Trisannabrücke) is a 211-metre (692 feet) long viaduct carrying the Arlberg railway over the Trisanna river just southwest of Pians, a district of Landeck (Tyrol) in Austria. The bridge spans the Paznaun valley and Trisanna gorge, forming part of one of the most important east-west railway routes in the Alps.

At the time of its completion in 1884, it was the longest steel support structure in the world.[1] It is still considered by many to be amongst the finest bridges in Austria,[2] and is overlooked on its eastern side by Wiesberg Castle. Together with the castle, the bridge has formed the backdrop for thousands of railway photographs.
