"The “twisted” bridge has spanned the Borne since the 14th century. It measures 84 meters for 6 arches. The spouts of the bridge that protect the piers are almost all pointed except for the last two which were redone following the flood of 1820. The bridge bears the nickname “twisted” since it is built on several different axes.

To guarantee its solidity, the builders of the Middle Ages ensured that the structure remained perpendicular to the current. The evolutions were made according to the displacement of the bed of the river.

This practice, already commonly used on other bridges such as that of Estrouilhas or that of Sumène, consists in lengthening the bridges in successive sections as the bed of the river moves by ensuring that the part construction of the structure is perpendicular to the course of the waters to better resist them.

The river was a necessary passage between the city of Le Puy and the outside. The “Tordu” or Roderie bridge allowed the inhabitants of Aiguilhe and Le Puy to reach their properties located on the slopes of Chosson by the shortest route. "

"Le pont « tordu » enjambe la Borne depuis le XIVème siècle. Il mesure 84 mètres pour 6 arches. Les becs du pont qui protègent les piles sont presque tous pointus sauf les deux derniers qui furent refaits suite à la crue de 1820. Le pont porte le surnom de « tordu » puisqu’il est bâti sur plusieurs axes différents.

Pour garantir sa solidité, les bâtisseurs du Moyen Age ont veillé à ce que l’ouvrage reste perpendiculaire au courant. Les évolutions se sont faites en fonction du déplacement du lit de la rivière.

Cette pratique, déjà utilisée couramment sur d’autres ponts comme celui d’Estrouilhas ou celui de la Sumène, consiste à allonger les ponts par tranches successives au fur et à mesure que se déplace le lit de la rivière en faisant en sorte que la partie en construction de l’ouvrage soit perpendiculaire au cours des eaux pour mieux leur résister.

La rivière était un passage obligé entre la ville du Puy et l’extérieur. Le pont « Tordu » ou de Roderie permettait aux habitants d’Aiguilhe et du Puy de gagner par le plus court chemin leurs propriétés situées sur les coteaux de Chosson."
