Etymology

Origin of viaduct

1810–20; < Latin via way + (aque)duct

Explanation

A viaduct is a bridge made of connected sections. Most viaducts are a series of arches that span a road. Some viaducts stretch across train tracks, while other carry traffic across valleys, gorges, or bodies of water. What's distinctive about older viaducts is that they're usually made of equal-sized arches all linked into one long bridge. Newer viaducts can look simply like an elevated road or highway. The word viaduct combines the Latin via, or "road," with ducere, "to lead something."
