This volume: Follow Bea, Archie, Trudy, and Spencer (otherwise known as the BATS!) as they crisscross the globe using every type of bridge: beam, arch, truss, and suspension. From ancient low-slung rope bridges to modern hi-tech towers of steel, they'll traverse 'em all. Their journey will take them through history and connect them with new ideas and different cultures. Along the way they'll identify the dangerous forces trying to bring bridges crashing down, and how to defeat them. . . through engineering!
