A new book published to accompany the acclaimed BBC TV documentary series 'Bridge'. Why do bridges mean so much to us? Looking up at the soaring arch of a great bridge evokes powerful emotions: fear, a sense of adventure, and a memory of the earliest human attempts to overcome the raging torrent. This book explores the meaning of some of the most important bridges ever built, from early stone structures to the breathtaking feats of modern engineering. It looks at the ways that bridges bring people together, and why sometimes they can tear communities apart. Bridge is a unique record of people's ideas and dreams: from famous bridge builders to the homeless people who sleep beneath their creations.
