Reservoirs of the Plaine Saint-Denis (here, the smallest tank), located under the France stadium are one of the largest type of construction. It can hold up to 165.000m ³ of water. The irregular shape of the pillars is due to the construction technique by molding (digging the soil, concrete injection and clearing the land around the pillar).

The Bridge on the Mulatière is a work of almost 200 meters long. He was carried away by a flood in 1840. Rebuilt by the company Levallois-Perret (formerly Eiffel) in 1916, he was destroyed by the Germans in 1940 and 1944. Contemporary life is much quieter. It provides rail traffic in the Lyon Saint-Etienne.
