Lers Aqueduct (French: Aqueduc de Lers) is one of several aqueducts, or water bridge, created for the Canal du Midi. Originally, the canal crossed the Hers-Mort on the level. It is near the village of Villefranche-de-Lauragais. The structure was completed in 1806 and designed by Jean-Polycarpe Maguès, chief engineer on the Canal du Midi.
