bridge construction materials

Bridge construction relies on a mix of materials, each chosen for strength, durability, and cost-effectiveness. Common materials include steel, known for its high tensile strength; concrete, which is strong under compression; and wood, often used in smaller or temporary bridges. Reinforced concrete combines concrete with steel bars (rebar) for added strength. Advanced materials like carbon fiber are also emerging for their lightweight and strong properties. The choice of materials affects the bridge's design, longevity, maintenance needs, and overall cost, ensuring it can safely support traffic and withstand environmental factors over time.
