1925+1951+2011 Térénez (Terenez) Bridges in France

(Satellite, 1,314 photos)

Note the suspension bridge in the background of this 2011 view. It has since been removed.

I've never seen masonry towers before for a suspension bridge.

The original bridge was destroyed by the German army in 1944. This one opened in 1951. It had a main span of 272m. [afgc]

The curved bridge avoids hairpin turns on both riverbanks without requiring either a very high bridge (expensive) or very deep cuts (damages the beautiful landscape).

The 1951 bridge was built on the piers of the 1925 bridge. Cracks were developing in the concrete, so it had to be replaced. [StructuresAndSpans and afgc]

I was going to skip yet another cable-stayed bridge until I noticed that the towers are very asymmetric. And then I noticed that the towers were asymmetric because the span was curved. I'm glad I researched this one because it is interesting.

The Térénez bridge is a cable-stayed bridge, located between Landévennec and Rosnoën, Finistère, France.
It is 515 meters long.

I was looking for a better view of how the cables attached to the top of the towers and discovered that the 1951 bridge lasted until at least 2014. It was gone in a 2018 view.

The pylons were built using jump forms.
