A pedestrian bridge is a structure designed specifically for people to walk across obstacles like roads, rivers, or valleys. These bridges help ensure safety by separating foot traffic from vehicles, making it easier for pedestrians to reach their destinations without the risk of accidents. Typically made from materials like steel or concrete, pedestrian bridges can vary in design and length. Some are simple walkways, while others may feature decorative elements or viewpoints. They are often found in urban areas, parks, and near attractions, enhancing accessibility and promoting walking as a mode of transportation.
