A footbridge is a small bridge designed specifically for pedestrians to cross over obstacles like rivers, roads, or valleys. These structures can vary in design and materials, often made from wood, steel, or concrete. Footbridges enhance safety by providing a dedicated pathway for walkers, reducing the risk of accidents with vehicles. Footbridges can be found in urban areas, parks, and rural settings, serving both functional and aesthetic purposes. Some famous examples include the Brooklyn Bridge in New York and the Millennium Bridge in London. They often feature unique designs that contribute to the surrounding landscape and can become popular landmarks.
