Terenez bridge, Cable-stayed bridge in Argol, France

Terenez Bridge is a 515-metre cable-stayed road bridge over the Aulne between Argol and Rosnoën. Its two light-grey concrete pylons rise from the water, each shaped like an inverted V with legs joined near the top, and fan thin cables down to a curved concrete deck with metal railings. The deck rests on a thick cylindrical pillar on the left bank.

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 appears in Rémi Bezançon's 2019 film Le Mystère Henri Pick during Jean-Michel Rouche's trips between Paris and Crozon, and at the start of Éric Lavaine's 2022 film Plancha. In June 2017 it was a filming location for the TV film Peur sur la base, set in the Brest roadstead. The Tour de France crossed it on 26 June 2021 during the first stage from Brest to Landerneau.

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.

The deck was built by cantilevering out from the pylons, the method typical of cable-stayed bridges, rather than by the suspension-bridge principle. Both pylons stand on the same side of the deck, which allowed the curved plan and helps stabilise the structure horizontally. The 2011 bridge cost about €35,000,000.
