A footbridge is like a special kind of bridge that is made just for people to walk on. It helps us cross over areas that we can’t walk across safely, like a busy road or a river. It’s kind of like a safe and enclosed walkway that lets us get to the other side safely. Footbridges can be made of different materials like wood, steel, or even rope, depending on where they are and what they need to do. They also usually have railings or walls to keep us from falling off. So, just like how you use a bridge to cross a small stream, people use a footbridge to cross other things that might be in their way.
