Bridge
HISTORY & CULTURESbeginner
Definition
A structure that spans a gap — over water, road, or valley — to allow passage. Bridges represent some of the most technically demanding and visually expressive works of engineering and architecture. Major bridge types include beam, arch, suspension, and cable-stayed.
Example
The Sydney Harbour Bridge (1932) — a steel through-arch of 503m span — was the world's largest steel arch bridge for 75 years and remains an icon of engineering and urban identity.
