Saint-Didier-sous-Riverie
The Bozançon River marks the point where the Aqueduct leaves behind the Gier Valley. Two bridges were constructed to cross the valley: the petit Bozançon, 46m long and the grand Bozançon; 28m.

Still in the Bozançon Valley, the most remarkable remains in this commune are the Jurieux bridge (16m long and 4m high with all 3 arches intact) and the Granges bridge (28m long and 10m high with 3 arches intact).
