Ever wonder how a bridge stays up-or why some stretch for miles while others are just a few steps long? This exciting nonfiction book for kids ages 7 to 12 takes young readers into the world of civil engineering with a focus on one of the world's most important inventions: the bridge.
Packed with real-world examples, clear explanations, and fun facts, this book unpacks the science, planning, and creativity behind building structures that hold cars, trains, and people above rivers, valleys, highways, and more. Readers will explore different types of bridges, learn the difference between tension and compression, discover why materials matter, and find out what happens when things don't go as planned.
From ancient wooden footbridges to today's record-breaking spans of steel and cable, the chapters explore how bridges are designed, tested, built, and maintained. Kids will also get an inside look at how engineers solve problems, work as a team, and come up with creative ideas to connect people and places.
Perfect for budding builders, curious minds, and future inventors, this book turns big engineering ideas into something kids can see, touch, and start thinking about on their own-whether they're crossing a local footbridge or dreaming up one of their own.
