Railway bridges are structures designed to carry trains over obstacles such as rivers, roads, or valleys. They are essential for maintaining efficient rail transport, allowing trains to travel uninterrupted across various terrains. These bridges can be made from materials like steel, concrete, or wood, depending on their location and the loads they need to support. The design of railway bridges often includes features like arches, beams, or trusses to ensure strength and stability. Notable examples include the Forth Rail Bridge in Scotland and the Brooklyn Bridge in New York, which showcase innovative engineering and have become iconic landmarks in their regions.
