The presence of transversal arches, many of which are empty in the interior, is a unique feature, which makes the Beaunant siphon bridge something quite exceptional.
The foundations of the receiving reservoir of the siphon have been found (not visible) on the south side of Sainte-Foy-lès-Lyon.
The Aqueduct next crosses the Sainte-Foy-les-Lyon plateau in what is practically a straight line, alternating between underground sections and above-ground ones carried on walls or arches (rue de Narcel and rue Georges Clemenceau). It then crosses the parc du Brulet where part of the underground channel is visible.
The Aqueduct then arrives in Lyon.
