Whether they span rivers or harbours, cultures or countries, bridges have long been a symbol of man's ingenuity, perseverance and thirst for exploration. Starting with ancient bridges built by the Mongol and Roman Empires through future bridges that exist only in blueprints, this volume travels the globe to examine 50 of the world's most important bridges and the history, legends and people behind them. In two-page spreads containing photographs, plans, drawings and text, this architectural and historical journey explains why bridges continue to fascinate us, both as examples of engineering genius and artistic vision. It reveals little-known facts that should deepen our appreciation of the science and technology of bridge-building, introduces historic events in which bridges have played a central role, and offers re-examinations of some of the world's most familiar bridges. From the glory of the Golden Gate, San Francisco, to the grace of the Ponte Vecchio, Florence, the imposing presence of London's Tower Bridge to a stone structure in Afghanistan's Quala Panji that is still used today, this volume is a celebration of our steadfast desire to connect with and discover the world around us.
