How Does a ‘Bridge’ Hold Up Traffic Without Breaking Down?

Bridges hold up traffic because they are strong and smart. Imagine a bridge as a big, strong arm, it bends just a little when cars drive over it, but it doesn’t break because it’s made of special materials like steel or concrete.

When you walk on a bridge, it feels solid beneath your feet. But actually, it moves, it stretches and squishes just a tiny bit. If the bridge is built right, this movement helps spread out the weight from all the cars and trucks that cross over it. This way, no single part of the bridge has to carry too much weight at once.

Think of it like a seesaw, if you sit on one side, the other side goes up, but neither breaks because they’re both strong enough to handle the movement.
