A moveable bridge is typically constructed from materials such as steel, concrete, and sometimes wood, depending on its design and purpose. The structural components, including trusses, beams, and decks, are designed to support the weight of traffic while allowing for movement. The mechanisms that enable the bridge to open or close, such as hydraulic systems or counterweights, are often made of durable metals for strength and reliability. Additionally, the surface of the bridge may be finished with asphalt or other materials to provide traction for vehicles.
