A fun, comprehensive, and lavishly illustrated guide to the bridges of the world for middle-grade readers.

This book fills a gap between picture books about bridges for elementary students and technical books about bridges for university coursework. It provides a readable but comprehensive and richly illustrated guide to bridges of the world, with attention to different designs (arch, beam, truss, cantilever, suspension) and materials (wood, stone, concrete, iron, steel, and even roots, grass, and plastic). Examples are drawn from across the world and across the centuries. Fun chapters include those on bridge disasters and the scariest bridges. The style is friendly and accessible, and the book includes links to online bridge-making activities from Carnegie Mellon University.
