The Pont de Saint-Pierre-du-Vauvray is a road bridge over the Seine in Saint-Pierre-du-Vauvray in the Eure department in the French region of Normandy .
The bridge leads the route départementale D313 over the left main arm of the Seine to the Île du Bac ( ferry island ). From there the road crosses another bridge to the right bank of the river.
description
The Pont de Saint-Pierre-du-Vauvray has two vehicle lanes and two narrow sidewalks on both sides.
The bridge, designed by Eugène Freyssinet and first built in 1922 and 1923 by Entreprises Limousin (Procédés Freyssinet) , essentially consists of two concrete arches to which hangers with cross girders are attached to support the deck. When it was completed, it was the concrete arch bridge with the largest span in the world .
The bridge structure, including the abutments that are largely in the ground , is 159 m long. The two clamped, parabolic concrete arches have a span of 131.80 m, whereby the arch attachment to the abutments is largely in the ground and can hardly be seen. The arrow height of the arches is 25 m. The arches are hollow boxes made of lightly reinforced concrete, the height of which is reduced from 4.10 m at the abutment to 2.50 m at the apex. Their wall thickness decreases from 0.60 m to 0.33 m at the apex. At a center distance of 5.24 m, the box girders are reinforced by panes that serve as fastenings for the hangers. The two arches are only connected and stiffened by two groups of cross braces at a height of 5 m above the roadway.
The hangers each consist of 40 thin steel rods that have been covered with concrete to protect against corrosion. Prefabricated cross girders made of reinforced concrete framework structures are attached to them, which support the bridge deck.
The bridge was blown up in the Second World War in 1940 by French pioneers and rebuilt almost identically after the war in 1946 and 1947.
It has been a listed building since 1975.
