Stone bridges were built to get over rivers etc, before iron or steel was used.
Favorite materials for bridges include steel, aluminum, titanium, wood, stone, and reinforced concrete.
Bridges built in the 1800s were typically constructed of wood or stone. Some bridges were also starting to be constructed of steel in the early 1800s.
The most common materials used in bridge building are generally steel or concrete for larger bridges, and stone or wood for smaller bridges.

Arch bridges are made from arches. Arches are typically made from brick, reinforced concrete, stone or steel. Wooden arches are sometimes used for ornamental bridges, such as decorative footbridges in gardens.
