Megastructures: Tallest, Longest, Biggest, DeepestMegastructures: Tallest, Longest, Biggest, Deepest

By Ian Graham

Bridges and tunnels are lifelines. People have tackled seemingly insurmountable obstacles, including  vast canyons and mountain ranges, to design and construct these amazing passageways. Bridges and Tunnels: Investigate Feats of Engineering invites children ages 9 and up to explore the innovation and physical science behind structures our world depends on. Trivia and fun facts illustrate engineering ingenuity and achievements. Activities and projects encourage children to learn about the engineering process and  to embrace trial and error.
