A tour of some of the world's greenest structures.

Building bridges across rivers, canyons, straits and sea represents one of man's greatest endeavours. It has stretched human ingenuity, engineering and material technology to their utmost limits. Their creation has been driven by man's desire, from the earliest times, to make lines of communication possible by foot, horse or engine. Bridges have altered history by joining communities together, extending trade and transporting water to villages and cities. Some are of breathtaking beauty and it is little wonder that they rank among the world's most admired structures. As Marcus Binney writes, 'Each one is remarkable in its own way, each a response to a challenge and perhaps the realization of a dream.' This book looks at more than two hundred bridges spanning the world and the centuries. Here you will find, amongst others, an Inca suspension bridge made from grass ropes; the mile-long Roman aqueduct at Caesarea; the bridges of Venice; France's famous Millau Viaduct; the doubledecker, transporter, lift and stilt bridges produced by German precision engineering; Spain's Acueducto del Aguila (glowing in a bright livery of yellow and terracotta red); the awe-inspiring cantilever bridges built by railway engineers across major rivers in North America and India, and the world's longest suspension bridge at Kobe in Japan.

Bridges are some of the most fascinating structures in our landscape, and they come in all forms. From towering suspension bridges to humble stone crossings, this book visits them all in sweet, bouncing text with expository sidebars. But while bridges can be quite grand, this reminds us that their main purpose is bringing people together. This is perfect for budding architects, as well as readers who can relate to having loved ones who live far away.

Photographs of ninety-five of the most impressive bridges in the United States are presented chronologically, from pre-Civil War spans to today's suspension bridges

Bridges and dams are key symbols of civic development, says Jackson and for this reason these two seemingly diverse types of structures have been combined in this book. The descriptions of many of the sites listed here go beyond simple data related to their dates and dimensions. The bridges and dams have been placed in historical contexts that illuminate their technological origins, the nature of their operation or their role in the local region's socioeconomic development. These analyses are designed to demonstrate the significance of these structres in America's history. ISBN 0-89133-129-8 (pbk.): $16.95 (For use only in the library).

Have you ever wondered how bridges don't fall down? Or how really old buildings stay standing up? In the How Do series, readers are welcome to guess along with the rest of us-and then explore the science behind the right answers. Basic principles of architecture and engineering, including an introduction to bridges, locks, arches, columns, and skyscrapers are explored through diagrams, photos, and informative and engaging text.
