Built at the end of the 15th century, it succeeds to a 12th century bridge and was a new access to the right bank of the Rhône towards the canton of Vaud. Built in stone and with only one arch, it is of a perfect technique for its time. Located on the gorge, it facilitated both the control of trade and the defense of the town. The bridge is dominated by the castle of Saint-Maurice which used to control the crossing.
