The bridge owes its name to the ruins near the medieval tower of Estiveaux, demolished during the Revolution. Like other medieval works, it is also sometimes referred to as the “Roman bridge”. It is made up of three semicircular arches, the two supporting piers of which are protected by convex flanks forepeaks. On the downstream side, there are no stops or refuges. A low wall serves as a parapet.
