bridges

Bridges are structures built to span physical obstacles, such as rivers, valleys, or roads, allowing people and vehicles to cross from one side to the other. They play a vital role in transportation and infrastructure, facilitating trade, travel, and communication. Bridges can be designed in various styles, including beam, arch, and suspension, each chosen based on factors like distance, height, and the weight they need to support. Their construction involves engineering and materials science to ensure safety, stability, and durability, serving as critical links in our transportation networks.
