Celebrate more than 100 bridges from around the world in this informative picture book that highlights human innovation, the science of engineering, and global community. Bridges accomplish many things--they span obstacles (rivers and canyons); they join places (cities and states and even countries); and they carry cars, trucks, and trains to deliver essential goods (food and clothing). Above all, bridges are feats of human innovation that bring people together. This essential STEAM offering celebrates these spectacular wonders of architecture and engineering, including examples found in nature, different styles and materials used in their construction, and the science behind how they work. It's a one-stop information panoply for young readers on all there is to know about these magnificent structures that unite people throughout the world.
