viaduct

Meanings

1. 1
   noun

   a long bridge, typically supported by a series of arches or spans, that carries a road or railway across a valley, low ground, or another obstacle

   The railway crossed the valley on a stone viaduct supported by tall piers.

A modern formation from Latin via, 'road or way,' + duct, modeled on aqueduct. The second element comes ultimately from Latin ducere, 'to lead,' so the word names a structure that leads a road or railway across an obstacle.
