Roman aqueduct
Rome's first aqueduct was built in 312 BC, and supplied a water fountain at the city's cattle market. By the 3rd century AD, the city had eleven aqueducts, sustaining a population of over a million in a water-extravagant economy; most of the water supplied the city's many public baths. Cities and towns throughout the Roman Empire emulated this model, and funded aqueducts as objects of public interest and civic pride, "an expensive yet necessary luxury to which all could, and did, aspire".
Duck Creek Aqueduct
Duck Creek Aqueduct, also known as the Metamora Aqueduct and Whitewater Canal Aqueduct, is a historic aqueduct carrying the Whitewater Canal over Duck Creek in Metamora Township, Franklin County, Indiana. It is the only surviving covered wood aqueduct in the United States as such it is a form of covered bridge. It is a single-span Burr through truss aqueduct and measures approximately long, wide, and deep. The original aqueduct was built between 1839 and 1843. The present structure was built in 1846, after the original aqueduct was washed out in a flood. It was strengthened in 1868, and repaired in 1901. After abandonment and deterioration, the Duck Creek Aqueduct was restored to its present appearance in 1946-1949.
