The method of freshwater transport that was essential to the Romans for trade was the extensive network of aqueducts and rivers. Aqueducts were remarkable engineering feats that transported fresh water from distant sources into cities and towns, supporting urban populations and agriculture. Additionally, rivers, such as the Tiber and Po, facilitated trade and transportation, connecting various regions of the Roman Empire. The ability to move goods efficiently supported economic growth, commerce, and the exchange of culture. The Roman infrastructure for water and transport played a critical role in expanding their empire and maintaining urban centers.
