The ancient Romans also had a complex system of aqueducts, which were used to transport water across long distances. The first Roman aqueduct was built in 312 BCE. The eleventh and final ancient Roman aqueduct was built in 226 CE. Put together, the Roman aqueducts extended over 450 kilometers, but less than seventy kilometers of this was above ground and supported by arches.
Welland
The First Welland Canal was extended in 1833 to reach Lake Erie and has influenced development of this city ever since. A wooden aqueduct was built to carry the Welland Canal over the Welland River at what is now downtown Welland, and the area became known as simply Aqueduct. A lock to cross from the canal to the river and vice versa was also built. A small shantytown soon developed around the facility, providing essential services in what was a convenient stop-over location for travelers and workers on the canal.
