The old stone viaduct arched gracefully across the valley, a testament to the engineers' skill.

The engineers inspected the half viaducts along the coastline to assess damage after the storm.

The mountain road includes a half viaduct where the hillside supports one side of the carriageway while the structure supports the other.
