👉 A footbridge is a type of bridge that spans only one side of a body of water or road, typically crossing over and connecting two sides. It is often used for pedestrian access to a narrow area of land such as an island or boat ramp. These bridges are typically made of wood or metal, with supports on either end that support the deck above the water surface. The deck may be raised or lowered depending on the use of the footbridge and the availability of space in the surrounding area.
