Opis

Bridges hanging on wires? Tunnels under rivers? Raceways two miles long? A football field that has a roof? A dam that holds back a raging river, and provides power? These and more were thought to be impossible, but they were built by some of the very few construction genius builders born every generation who refuse to believe in "impossible" projects, and go ahead and build them. In this book are the first, when today's construction science was not available and when most people felt such massive projects couldn't be done. They were done. Man has landed on the moon, but this was the first time. And they built a great arch. And they carved a mountain top. And more.
