The Pont de Tonneins is the only bridge to the right bank of the Garonne situated town Tonneins in the department of Lot-et-Garonne in the French region Nouvelle-Aquitaine connects to the areas south of the river.
The road bridge with two lanes and narrow sidewalks on both sides leads the départementale D120 over the river. It has five openings with wide, flat arches over the river and each a narrow round arch in the abutments for a passage on the bank. The road surface rises slightly from both sides towards the middle of the largest arch.
In his design of the bridge, Eugène Freyssinet adopted stylistic features of the Pont Neuf, completed in 1632 in Toulouse , 160 km away upstream : the piers do not protrude very high out of the water. The light gray reinforced concrete arches running make great above the pillars, completed also with light gray arches openings clear that the lion's mouths or Geuloirs remember the Pont Neuf. As in Toulouse, the remaining areas of the gusset were clad with bricks. If you look into the openings you can see that the gussets consist of six thin, parallel concrete slices with open spaces. The construction with reinforced concrete not only allowed wider and lighter-looking arches, but also a carriageway slab that clearly protruded over the arched structure.
The openings are intended to reduce the water pressure on the bridge during floods. The Garonne rises again and again so high that water flows through the openings.
The structure is 240 m long, including the abutments. The distance between the pillars of the main openings is 41.5 m for the central opening and 37.5 m for the side openings.
history
The first bridge at this point was a 194 m long suspension bridge with three openings built by Jules Seguin and Ferdinand Jean Bayard de la Vingtrie in 1832 .
The current bridge was built by the Entreprises Limousin (Procédés Freyssinet) between 1919 and 1922 according to Freyssinet's design .
