Terenez bridge

Terenez Bridge is a cable-stayed road crossing that runs 515 meters between two shores. Its single pylon supports steel cables that carry the weight of the curved deck, creating an asymmetric profile over the water.

The current crossing opened in 2011 after the previous one from 1951 had to be demolished. Engineers found that chemical reactions inside the concrete had weakened the old structure beyond repair.

The bridge represents a milestone in French engineering, incorporating advanced construction techniques while connecting communities in the Brittany region.

The crossing links the Crozon peninsula with the northern part of Brittany and carries both local traffic and travelers in Finistère. Pedestrians and cyclists use protected pathways running alongside the roadway.

Construction workers built the curved deck without scaffolding in the water, pushing sections forward from both ends. This method reduced interference with the river and cut down the time needed to finish the work.
