Question

Three materials from which arch bridges are typically made from

Answer 1

Arch bridges are typically made from stone, concrete, and steel.

Step-by-step explanation:

Arch bridges are typically made from three materials:

1. Stone: As seen in the Pont-du-Gard aqueduct in France, stone is a durable material that can withstand the weight and pressure of an arch bridge.
2. Concrete: The use of concrete in arch bridges allows for the construction of larger and more expansive structures, such as vaults and domes.
3. Steel: In modern arch bridge construction, steel is often used due to its strength and flexibility, allowing for lightweight and efficient bridge designs.
