Wikipedia:<br>Since 1995, studies on a new bridge were undertaken with an improved traffic management. By the bridge engineer Michel Virlogeux, the architect Charles Lavigne and representatives of the Sétra (service d ' études sur les transports, les routes et leurs aménagements - a State Bauplanungs-,-beratungs-and monitoring institution) created design for a bridge about 60 m below the existing was finally accepted for execution.

It is a cable-stayed bridge with a trending in a large curve track to the roads as wide arches join. These lines was possible by the significantly higher compared to the old bridge the deck, so that the access roads above the steepest sections in shallower parts of the Valley slopes could be built. On both sides of a pylon inclined outwards, which is supported under the pavement by a slanting pillars, so that results in a large lambda is each on the inside of the curve of the road. On the pylons 72 pairs of cable in the fan system are fixed, the untere ends on both sides of the curved road fixed, what are technically represents an orderly system, from the point of view of moving across the bridge Viewer but arising constantly changing arrangements and multiple overlapping of the ropes.

The bridge structure is a total 515 m long. The large opening over the river has a central span of 285 m, the two lateral boxes have 7.50 m spans of 81,25 m and 33,70 m. [3] which is a road with two lanes wide; outside the cable fixtures, wide paths for pedestrians and cyclists join each 2.40 m. The road curve in the middle section has a radius of 800 metres, the more curved driveways have a radius of 200 m. The deck consists of prestressed concrete and was created in the cantilever with 7.50 m long concrete sections.

The pylons are nearly 100 m high and are also made of prestressed concrete. Their cross-section tapers first of all, to be below the rope anchoring again widen, which placed special demands on the self climbing formwork. The top of the pylons to anchor block for the ropes, which was lifted by a crane in one piece to the Assembly located in each a 119.

Builder of the bridge is the Conseil Général du Finistère. The construction works started in April 2007 were carried out by VINCI Construction France in collaboration with several of its subsidiaries.[4] On April 16, 2011 the bridge was inaugurated, among others with a bicycle race.
