Beam bridge
A beam bridge is like a really long, flat board that goes over a river or road. It's made out of strong materials like steel or wood so that cars and trucks can drive over it without any problems.
The bridge has strong supports called pillars or piers. These are like big legs that hold up the bridge and keep it from falling down.
When you walk across a beam bridge, you might notice that it bounces up and down a little bit. This is normal and nothing to worry about. The bridge is designed to move a little bit so that it doesn't break when something heavy travels over it.
Beam bridges can be found all over the world. They are very useful for helping people get from one side to the other without having to swim or take a really long detour.
