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 navigate busy areas. They can be found in urban settings, parks, and near schools. Typically made from materials like steel or concrete, pedestrian bridges come in various designs, including arch, beam, and suspension styles. Some famous examples include the Brooklyn Bridge in New York and the Millennium Bridge in London. These structures not only serve a functional purpose but also enhance the aesthetic appeal of their surroundings.
