Definition
Noun: A viaduct is a long bridge-like structure, typically consisting of a series of arches or spans supported by tall piers or towers, used to carry a road or railway across a valley, gorge, or other low-lying ground.
Usage
A viaduct is a specific type of bridge designed for transportation infrastructure. It is characterized by its length and its use of multiple, relatively short spans (often arches) to traverse uneven terrain without requiring a single, massive span. It is distinct from a simple bridge, which may cross a river or road with fewer supports.
Examples
- The old railway viaduct crosses the entire river valley.
- The new highway project includes a long viaduct to connect the two hills.
- Engineers are inspecting the stone arches of the historic viaduct.

- The disused railway viaduct has been converted into a public walkway.
- "Elevated viaduct": A viaduct built in an urban area to carry traffic above ground level.
- The city's traffic flows smoothly on the elevated viaduct.
