Did You Know?
Based party on the Latin ducere, meaning "lead" or "conduct", the word aqueduct named an ancient civil-engineering marvel. You may have seen photos of the great arches of ancient aqueducts spanning valleys in countries throughout the old Roman Empire, practical pipelines that are also regarded as works of timeless beauty. From the 20th century, the 242-mile Colorado River Aqueduct, the 336-mile Central Arizona Project, and the 444-mile California Aqueduct are considered wonders of American engineering, but they are not renowned for their beauty. Most aqueducts today either are riverlike channels or run underground, perhaps appearing simply as a long mound.
