Trisanna Bridge

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. It is still considered by many to be amongst the finest bridges in Austria, 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.
