Bridges are everywhere. They help us cross rivers, highways, and even entire valleys. But have you ever wondered how engineers make sure they don’t collapse? It all comes down to smart design, strong materials, and physics.
Engineers use different types of bridges depending on what they need. Suspension bridges, like the Golden Gate Bridge, use strong cables to hold up the road. Arch bridges, like the Sydney Harbour Bridge, spread out the weight so they don’t crumble. Truss bridges, made of triangular shapes, are great for holding heavy loads.
To make bridges safe, engineers test materials like steel and concrete to see how much weight they can handle. They also have to think about things like wind, earthquakes, and even the weight of cars and trucks. Without this careful planning, a bridge could be unsafe.
Next time you drive or walk across a bridge, think about the amazing engineering that went into it. It’s not just a road in the air—it’s a masterpiece of science, math, and creativity.
