Imagine you want to go from one place to another, but there are too many cars on the road and it's taking forever. Well, skyways are special roads built up high in the sky so that cars, buses, or trains can travel without getting stuck in traffic.
These skyways have super strong structures holding them up and they go over other roads and buildings so that they don't get in the way of anything on the ground.
People like using skyways because they can get to their destination more quickly and easily. Plus, they get to see everything from way up in the sky!
