A steel bridge is a type of bridge constructed primarily from steel, known for its strength and durability. Steel bridges can be designed in various styles, including beam, truss, or arch configurations, allowing them to span long distances while supporting heavy loads. They are commonly used for roadways, railways, and pedestrian crossings due to their ability to withstand harsh weather conditions and environmental factors. The use of steel in bridge construction also allows for lighter structures compared to those made from concrete, making them easier to transport and assemble. Steel bridges are a popular choice for modern infrastructure projects.
