Yes another aqueducto - but a big one. It is part of the 50 km long Nimes aqueduct which while mostly underground required a large bridge to cross the Gardon River. It is the highest of all the Roman aqueducts (nearly 50m tall) and as the water crossed the bridge it dropped a mere 2.5 cm. In fact in the whole 50 km to Nimes, the drop was was only 17m. After the Romans left it fell into disrepair but the lower tier continued to be used as a toll bridge for centuries.
